Indeed.
Except, as explained in my previous post, the overload method
can't just build and return a qr// each time its invoked, because:
(a) it needs access to the entire contents of the original regex
including the contents of interpolated variables (so it needs
to use the return-an-object-that-accumulates-concatenations
technique), and
(b) even if it didn't need to accumulate interpolations, any code
blocks in the original regex wouldn't then close over the
correct variables, having been qr'd in the lexical scope of
the overload sub, rather than the lexical scope of the
original regex.
