The semantics are:

    applied any bound variables

0d13b5e3bc Preliminary support for binops in if-discriminators 
The BNF grammar is a bit more liberal than any successfully-compiled
schala program should be, in that it allows things like `if x < is
pattern`. It's okay if that parses successfully and then is an error at
typechecking.
