There is a considerable learning curve, but that is mainly the learning
curve of compiler construction / language recognition etc. I found the
actual learning curve for ANTLR to be quite easy.

Well, it's probably possible to get this working somehow quite quick.
But the question is if that is actually helpful for you. I'd bet that
you're not trying to build a "calculator that supports booleans" but
something more complex. And in that case you will probably not succeed
with something hacked together quickly.
