Thats a very good point. The problem is that wordforms currently don't have a good way to describe having multiple choices (which is why the whitespace example is so verbose). Choice blocks are verbose however. Do you have an idea of what better syntax would look like?

Yes and no. The 'anychar[]' and 'anyindex' feature is extremely powerful and can be used to put arbitrary constraints on a variable. What are you asserting that they are redundant with?

Btw, thanks for delving so deep into this - I appreciate the feedback.
