What's so bad about that?  The stack wouldn't carry over after <html></html>
or <body></body> - couldn't practically more than 1000's - insignificant!

Point is, it's slow and inefficient, and a clunky syntax.  Reasons the whole
idea of 'else' was invented in the first place.  I worry, that ZPT is
benchmarked 4x slower than DTML and it's becoming the standard - not a step
forward.  And issue like this haven't been satisfactorily resolved.

I think, if it's going to have logic in there, make it sufficiently powerful
and efficient.  Otherwise get rid of it altogether, unapologetically, and
require Python for such things....
