in reply to Diff between 'print POSIX::cuserid' and 'use POSIX; print cuserid'
In your first example, you did a use POSIX; in the second, you did not. Why?
Without loading POSIX you won't be able to call a function like POSIX::cuserid.
EnableBut with loading POSIX:$ perl -wE 'say POSIX::cuserid' Name "POSIX::cuserid" used only once: possible typo at -e line 1. say() on unopened filehandle cuserid at -e line 1.
$ perl -MPOSIX -wE 'say POSIX::cuserid' linuxer
Updates
- replaced strict with warnings; removed strict from code examples; the warning is the crucial part.
