mal/hy/step1_read_print.hy
Joel Martin dd7a4f55f3 Test uncaught throw, catchless try* . Fix 46 impls.
Fixes made to: ada, c, chuck, clojure, coffee, common-lisp, cpp,
crystal, d, dart, elm, erlang, es6, factor, fsharp, gnu-smalltalk,
groovy, guile, haxe, hy, js, livescript, matlab, miniMAL, nasm, nim,
objc, objpascal, ocaml, perl, perl6, php, plsql, ps, python, r,
rpython, ruby, scheme, swift3, tcl, ts, vb, vimscript, wasm, yorick.

Catchless try* test is an optional test. Not all implementations
support catchless try* but a number were fixed so they at least don't
crash on catchless try*.
