NAME

span - Provide Haskell's span functionality

SYNOPSIS

use span;

.say for span * < 10, 2, 2, 2, 5, 5, 7, 13, 9, 6, 2, 20, 4;
# (2 2 2 5 5 7)
# (13 9 6 2 20 4)

.say for span (* < 10, * < 20), 2, 2, 2, 5, 5, 7, 13, 9, 6, 2, 20, 4;
# (2 2 2 5 5 7)
# (13 9 6 2)
# (20 4)

.say for span Int, 2, 2, 2, 5, 5, "a", "b", "c";
# (2 2 2 5 5)
# (a b c)

DESCRIPTION

The span distribution exports a single subroutine span that mimics the functionality provided by Haskell's span functionality. But only if the core does not supply a span subroutine already (which it may at some point in the future).

The span subroutine takes a matcher much like grep does, which can be a Callable or any other object that can have the ACCEPTS method called on it.
