Add more TLA+ operators if necessary #3

Closed minhnhdo closed 6 years ago

minhnhdo commented 6 years ago

PlusCal may support some TLA+ operations that may not be found in the TLAExprParser token dictionary. If these exist, we need to add them to the dictionary and handle them properly.

The most important operators that are not parsed (properly) are the Cartesian product operator \X, the IF...THEN...ELSE expression and CASE construct, and the DOMAIN operator. It is also possible to use multiple |-> operators in one map declaration, like in ["a" |-> 1, "b" |-> 2, "c" |-> 3].

Closing this since the classes mentioned no longer exist (and we now support IF and CASE expressions).
