That's a problem with any lisp that provides a reader-macro facility.
The onus is on the authors of macro packages to create macros that work
well with the existing emacs-lisp-mode parser.

We already have plenty of libraries defining "control flow" structures;
look at all the anaphoric-if libraries out there. ITYM "lexical
structure", not "control structure".
