st: Use extended functions outside of macro assignment?

I keep running into situations where I would like to use an extended function
as a part of a function call, e.g. in a conditional statement. I thought I had
seen syntax to do this before, but I cannot find this now.
For example, let's say I wanted to operate on a set of observations dependent
upon some characteristic of a value label, say that the value label matches
some regular expression. How can I do this? I specifically cannot pull the value
label into a string variable with decode due to the size of the dataset:
Something like this:
list if regexm("`: label (varname)'", "my_regex")
or say I want to operate on a set of ids I have stored in a local macro "ids":
list if `: list posof id in ids'
