There was a problem hiding this comment.
It looks like if we had a way to const-fold expressions into int we could just check it like:
m["n"].ConstValue.Int() <= 0
It's not hard to implement, actually.
What do you think?

- Where(m["n"].Const && m["n"].Text.Matches(`(\-[0-9]+|0)`))
+ Where(m["n"].Value.Int() <= 0)

Added Value expression field that can be used to check the submatch value. Since `go/types` has some const-folding out-of-the-box, we get it too. Right now only `int` value types are supported, but we could extend the set of types later. This is a proof-of-concept that can be useful in #96. Signed-off-by: Iskander Sharipov <[email protected]>
