The "each" function is generally discouraged due to implementation details,
but is still the most "pretty" and concise way to write such a loop:
while (my ($key, $value) = each %hash) { ... }
A possible alternative to this would be a syntax to alias multiple items
per iteration in a for/foreach loop.
foreach my ($key, $value) (%hash) { ... }
This could be generalized as a "bundler", in other words to alias a number
of elements from the list equal to the number of variables specified. Such
as:
foreach my ($foo, $bar, $baz) (@array) { # $foo, $bar, and $baz are the
next three elements of @array, or undef if overflowed
I can think of one syntactical issue presently: "foreach ($foo, $bar)"
without the "my" is already valid syntax so would be difficult to
disambiguate without looking for the second () denoting the list to iterate
through.
Thoughts?
