In this example

where does the match function come from?
I get this error when trying to compile:
onlineapp.d(16): Error: no property match for type int
/dlang/dmd/linux/bin64/../../src/phobos/std/algorithm/iteration.d(500):        instantiated from here: MapResult!(__lambda1, int[])
onlineapp.d(15):        instantiated from here: map!(int[])
