-// i'm studying compilers using "modern compiler implementation in ML" by Andrew Appel
-// translating to Kind as I go. i'm not too worried about following the book too closely.
-// for example i'll likely use kind's `Parser` to parse programs instead of Lex and Yacc.
-// but i'm using ML's naming conventions. it looks ugly but makes lookups easier.

-// position on source code, to produce error messages
