=head1 NAME

PerlX::ifor - A version of for() that accepts iterator instead of list

=head1 VERSION

This document describes version 0.001 of PerlX::ifor (from Perl distribution PerlX-ifor), released on 2019-04-16.


With L<Array::Iter> or L<Range::Iter> which generates a coderef iterator:

 use PerlX::ifor;
 use Array::Iter qw(array_iter list_iter);
 use Range::Iter qw(range_iter);

 ifor { say } iter_range("a", "z");


CAVEAT: Yes, it's ugly and doesn't look like a regular for(). Sue Perl :-)

TODO: Support other iterator, e.g. L<Array::Iterator>.
