At an attempt to take your question seriously, you probably mean the remove program as used by cmd.exe on Microsoft Windows. I suspect that your experience is limited to just that one operating system and just that one shell (cmd.exe, that is). Other operating systems and environments have other names for that. unlink is the name of the UNIX kernel function to delete a file, it is called DeleteFile by the Windows kernel, but 'remove' at the Windows command line and 'rm' at the UNIX command line. I have no idea what it is called on MAC, IBM Mainframe, VMS, or mumble-mumble.

So, whatever Perl had called it, someone would have complained that it was not the same as they are used to. Update: OK, I'm wrong again, the remove function is part of the ISO C library not cmd.exe, and Mr. Google tells me it is used in other places, like DB2, but I think my point still stands.
