This came up on #perl recently, why are the filetest operators in perlfunc? They sure look like unary operators to me. I wouldn't think to look for them amongst the functions. There's only one mention of them in perlop, and that's this. Regarding precedence, the filetest operators, like "-f", "-M", etc. are treated like named unary operators, but they don't follow this func- tional parenthesis rule. That means, for example, that "-f($file).".bak"" is equivalent to "-f "$file.bak"". Even the perlfunc entry says they're ops. -X FILEHANDLE -X EXPR -X A file test, where X is one of the letters listed below. This unary operator takes one argument Would anyone be opposed to their docs being moved to perlop? -- Stabbing you in the face for your own good.
