open Utils
(* Regions
The AST carries all the regions where tokens have been found by the
lexer, plus additional regions corresponding to whole subtrees
(like entire expressions, patterns etc.). These regions are needed
for error reporting and source-to-source transformations. To make
these pervasive regions more legible, we define singleton types for
the symbols, keywords etc. with suggestive names like "kwd_and"
denoting the _region_ of the occurrence of the keyword "and".
