The only reason I could think of to make this comment is if there were some other sort of variable

Or if someone posts an SoPW asking how to make it variable.

Actually, it was to say that there wasn't "some other sort of variable". The OP's supposition implied that variables could be used there. They can't. That's what I said.

Aside from that, did you forget about capture buffers, the return value of the last (?{ }) and Perl variables? There's just no way to access them there.

Update: Added second and third para.
