    Because you removed it! :) 

    $ perl -Mstrict -Mwarnings -e " print WNOHANG "
Name "main::WNOHANG" used only once: possible typo at -e line 1.
print() on unopened filehandle WNOHANG at -e line 1.

      WNOHNAG is defined in:

      use POSIX qw(:sys_wait_h); WNOHANG is a constant value. There is no "&" address of this constant value defined.

      Perhaps I should have said no & address of (&) operator is needed before a constant. And that it is wrong to do that.

      Updated with strikes.

        Um, in perl, & is not the address-of operator 

        $ perl -MPOSIX=WNOHANG -e "print WNOHANG, &WNOHANG"
