1abbe2e448 Add guard to Alternative
The semantics are:
    -if tag is Some(_), assume the condition is a constructor,
    and compare tags
    - if guard is Some(_), evaluate true/false *after* having
    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

065bdd6bda Starting custom operators
Can now parse custom operators. Maybe I want to make it so that you
have to put explicit backticks if you define a custom operator,
currently you can just do: fn +() { .. }

2c298c7247 Add warning for undefined operator
In practice this will probably always not typecheck, but it's a valid

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.
