1abbe2e448 Add guard to Alternative
The semantics are:
    -if tag is Some(_), assume the condition is a constructor,

    applied any bound variables

With this, I can technically get rid of bare conditionals now, since
they are the same as an Alternative with a None tag

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.
