Now, you must realise that "regdef" isn't magical.
Here's the grammar:
tstatement := "regdef" sdeclname "=" sregexp[ralt_pri] ";" =>#
"""
`(ast_val_decl ,_sr ,(first _2) ,(second _2) (some (ast_lookup ( ,(noi
'Regdef) "regex" ()))) (some ,_4))
""";
So you see, regdef just creates a "val" initialised to a data structure
specified in
the Regdef class, type regex:
class Regdef {
union regex =
| Alts of list[regex]
| Seqs of list[regex]
| Rpt of regex * int * int
| Charset of string
| String of string
| Group of regex
| Perl of string
;
So there's no magic. It's a simple user bug that the compiler SHOULD have
caught.
Let's rewrite it:
val binder = ... spaces ...
val spaces = ....
