Some kind of escape in parse rules might be nice. I haven't needed it
either but, if you're dealing with a small set of special numbers in a
particular situation, we can at least work around it. e.g.
make-int-rule: func [val][append copy [1 1] val]
make-int-rules: func [values [block!]][
foreach val values [
set to word! join '` val make-int-rule val
]
]
make-int-rules [2 27 94]
; I chose ` so it looks sort of like a lit-number! format. :)
print parse [2 27 94] [`2 `27 `94]
