In the "Bidirectional Communication with Another Process" section of perlipc.pod (git) is this example: use FileHandle; use IPC::Open2; $pid = open2(*Reader, *Writer, "cat -un"); print Writer "stuff\n"; $got = <Reader>; I'm curious whether "use FileHandle" serves any purpose there? The example seems (superficially at least) to behave identically with or without it, and no warnings are issued with strictures and warnings enabled (except for missing "my" on $pid and $got). Is it there maybe for pedagogical reasons or to illustate preferred usage? Anyway, if it's just a leftover or should be removed, let me know, I'll file a perlbug on it with a doc patch.Thread Previous | Thread Next
