"map" has become a keyword to introduce definition of maps by extension in declarations ("map" ... "end"). This entails that a grammar rule had to be created to handle the type expressions "map (..., ...)". Concordantly, I added map patches, modelled after record patches.
I created a node in the AST for map expressions (currently only
map look-ups).
I refactored the parser with parametric rules.
