greg c64f53a050 Detect duplicate variable declarations correctly
Later I'll probably want to make it so that you can explicitly override
the value of a declared variable

to symbol table
2019-03-07 20:45:12 -08:00
greg 0bcd7e6f41 Add new_env method
This is basically the same as the one on the evaluator and makes use of
the ScopeStack - maybe need to generalize this more?

greg b35262c444 Rename Node -> Meta 2019-02-21 01:49:15 -08:00
greg 9bb3a2be88 Add type data handle on Node
I think the way I want to handle this is a two-step process: first infer and
fill in variables, then unfiy in a separate step. Storing the data in
the AST is handy.

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

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.
