I took a stab at this one, but giving up for now.
Things discovered:
- It's the second `:that(5.3)` that is the thing causing the issue
- To repro the issue, instead of a Rat you can use a constant, e.g. `:that(pi)`
- ASTs:
- Working version has: QAST::WVal(Rat) <wanted> :statement_id<?> 5.3
- Broken version has: QAST::Want <wanted> (looks like it's missing stuff
inside of it, which is what gives the error)
- --target=parse:
- Working version has EXPR => - 0: colonpair: (first) - 1: colonpair:
(second)
- Broken version has EXPR => - 0: colonpair: (first) - fake_infix: -
OPER: - colonpair: (second)
So looks like the Actions for `statement` token needs to rake through
`fake_infix` capture and generate proper colonpair instead of empty QAST::Want.
I gave up at that point, but hopefully my digging will be helpful to someone :)
