I just got into the habit of sub declaration, because I remember warnings being generated if you didn't. Its all about parens. If you use parens, no warnings. You use parens :) `$ perl -le " f(1); sub f{warn@_} " 1 at -e line 1. $ perl -le " f 1 ; sub f{warn@_} " Number found where operator expected at -e line 1, near "f 1" (Do you need to predeclare f?) syntax error at -e line 1, near "f 1" Execution of -e aborted due to compilation errors. $ perl -le " sub f; f 1 ; sub f{warn@_} " 1 at -e line 1.` [download]	[reply] [d/l]

Defining a sub also "declares" it: `$ perl -le "sub f{warn@_} f 1" 1 at -e line 1.` [download]	[reply] [d/l]

Defining a sub also "declares" it Except when it declares it too-late for the parser to notice The OP uses parens, so the parser doesn't need a "forward" declaration or re-arranging of sourcecode	[reply]
