$iterator = Ierator::Flex::Grep->new( $coderef, $iterable );

Returns an iterator equivalent to running grep on $iterable with the specified code. $iteratable is converted into an iterator (if it is not already one) via $class-to_iterator>, which defaults to "to_iterable" in Iterator::Flex::Base).

CODE is not run if $iterable returns undef (that is, it is exhausted).

The iterator supports the following methods:

next
