This makes vim mode work again.
I don't know a good way to test this, since it involves dealing with
absolute paths. If anyone has the bash skills to get this working in a
pkg test, please do...
Can't export a type which refers to a private name. This has caught a
couple of visibility errors in the libraries, code and tests, so they've
been updated too.
Now all common console IO functions available from the
prelude are available through the `Control.App.Console`
interface.
Added:
- putChar
- getChar
- getCharLn
- print
- printLn
Renamed:
- getStr to getLine
Don't get too excited yet - I want this in so that it doesn't get too
out of sync, but I still have to think about exactly how it's going to
work in practice.
This means it abstracts over the value syntactically, rather than by
value, and can significantly speed up elaboration where large types are
involved, at a cost of being less general. Try it if "with" is slow.
There are more flags we want on with (well, at least one: "proof")
building Chez Scheme locally from source and
improve formatting of first paragraphs

As patterns weren't getting propagated to local definitions, due to a
combination of being stored as let bindings and being part of a pattern
scrutinee. The solution removes the computation behaviour, but that is
consistent with the way let works everywhere else.
(If we do as patterns as let bindings, the way case and locals elaborate
mean that the value gets recomputed. Fixing this would require changing
the way the core works, and I'm not going to do that for a while.)
The required totality of interface methods is now only affected if
there's an explicit modifier on the method. This allows us to set
%default total on the Prelude, which is a good thing to do anyway,
without also requiring that every implementation of the interface in the
prelude has to be total, which would potentially be a pain.
Another good affect is that it speeds up totality checking elsewhere
because totality checking is done lazily, and so with the total flag set
we know in advance that prelude functions are total.
On second thoughts, and after further experimentation, better to recheck
the metavariable if it arises in linearity checking, because the type
could be very big and in general will be much bigger than the
definition. If this turns out to be a performance issue later, we can
revisit it.
In this case, it's only needed to ensure the dictionaries are inlined
when checking recursive methods, so can be unset once we're done, to
save excessive inlining when totality checking later.
It's a small performance hit, but not as big as it used to be because we
don't load everything any more. This is necessary because saved
metavariables might turn up during evaluation, and then be needed in the
final linearity check. Another way is to check them again if this
happens, but there's a risk that might be even more expensive (and
saving the type is much safter anyway).
This wouldn't have got caught since the merge that caused the problem
was checked before I pushed the patch that made import work right! So
hopefully this'll sort it.
