Late Weekly challenge 67 #1 only

I wrote some library to make combination in 2013.

I think that finding combination isn't necessarily written using recursive calling.
so this is my first "working" solution.

it is possible to use some list of words (ex) "a", "b", "c" ) instead of number.

Just want to know WNOHANG...

package MyApp;
# I just want to know WNOHANG from sys_wait_h ... [-;

our $WNOHANG_VALUE ||= `$^X -MPOSIX=:sys_wait_h -e "print WNOHANG;"`;


sigh maybe useful for a long-time running program if you are sensitive to memory usage..
