There's light and day difference between the simple for() form with the
direct body and access to break, continue compared to forcing a lambda.
for_each may be considered as a workaround but by no means can count as
best or simplest solution -- especially for an artificial problem
planted into the language.

I absolutely want the language to evolve by fixing core facilities to
just work along original intended semantics without gotchas and chapters
to teach.
