Why single out for/while and leave out try? It supports an else
statement in a similar fashion.
Honestly I think the syntax is fine as it is. Once I grasped what it
did and why, I exploited it to great effect. The syntax may be
to programmers coming from other languages, but so what? The same can
be said of every language on the planet. (I felt like an idiot
when I started to learn Haskell).
FWIW, nothing in life is intuitive. Absolutely nothing. Everything
has to be learned, even the simplest things. A baby has to learn how
to nurse and many struggle with that unintuitive process as well. The
concept of what is "intuitive" is entirely in the eye of the beholder
and is effectively a non-concept.
