Importing grammar rules from a file

[jarble]

I often re-use the same grammar rules in multiple grammar files, so I want to save these rules in one file and import them into other grammar files.

If I defined a rule in a file named rules.peggy:

function_call = a1:var_name "(" _ a2:exprs _ ")" {return a1+"("+a2+")";}

I would want to import it into another grammar file:

import rules.peggy

Does Peggy have a feature that allows grammar rules to be imported like this?

We're currently talking about it here, and in a draft PR that isn't finished yet.

Also #417

I think #456 is the full fix for this.
