oops. well i’ll work on the regex some more later today. i have an idea of how it will work, hopefully it’s right.

[morganholly]

@RSDuck is it possible to put a case expression in an if/when/elif? it seems to not work, i'm getting errors from the extension, but if it does the regex i came up with wouldn't work there.

yes it's possible like this:

if (case range[0..1](1)
    of 0: false
    of 1: true):
  echo "miauz"

[morganholly]

does it require the parens?

[RSDuck]

I think yes, I cannot get it to work without them, though I'm not 100% sure.

Not at my computer, but I'm pretty sure it'dt be possible to do similar things in a bracket expression that evaluates to an array index for lookup.

Basically the nesting could be achieved in a few ways.
