NAME

snip - Provide functionality similar to Haskell's span

SYNOPSIS

use snip;

.say for snip * < 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 snip (* < 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 snip Int, 2, 2, 2, 5, 5, "a", "b", "c";
# (2 2 2 5 5)
# (a b c)

DESCRIPTION

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

The snip 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. Different from the Haskell's span implementation, snip can take multiple matchers to snip the origin list in more than 2 parts.
