greg 693766fa59 Proc macros are stable now 2018-09-21 19:46:31 -07:00
greg 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
 2018-08-27 12:45:08 -07:00
greg 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 +() { .. }

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

greg 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.

greg 348a6f7c76 More work on pattern-matching 
I think I need to entirely change the types in the evaluator.
ReducedAST should only care about NewConstructor (which I gotta rename),
and the evaluator is the only place that an implementation of a
primitive constructed type should live (see Peyton-Jones implementing a
functional langauge p. 70)
