A patch to fix the issue
What was happening was:
1. Factory.create(123) is desugared into CommaExp: (Factory,
This is done in CallExp::semantic when the method is static template method.
I'm not at all sure but is this for keeping side-effects for some cases?
2. In e2ir.c TypeExp::toElem emits the compilation error; it tries to compile
lhs and rhs into IR, but TypeExp cannot be compiled to IR.
The patch modifies the first point. If the expression is "TYPE . SOMETHING",
the CommaExp insertion is disabled.
FYI, the problematic error is issued only inside ThrowStatement, because
in ThrowStatement::semantic, exp->optimize() is not called.
In, e.g., ReturnStatement::semantic optimizes away the TypeExp before toIR
convertion, so it won't cause any problem. (I don't know the reason why.)
