Re^3: Chomp(<handle>)

$ perl -e 'chomp(" foo ");'
Can't modify constant item in chomp at - line 1, near "" foo ")"

$ perl -e 'chomp(<STDIN>);'
Can't modify <HANDLE> in chomp at - line 1, near "<STDIN>)"

Different error messages. In the first case, it complains about modifying a non-lvalue (a constant item). In the second case, it complains about modifying the results of reading from a file handle.

I'll grant you that chomp SCALAR can't chomp a non-lvalue, if you'll grant that the ambiguous context of the syntax chomp <FOO> is another valid reason that the compiler gives a separate distinct message.

In the second case, it complains about modifying the results of reading from a file handle. Care to place a small wager on that? I could be wrong. You might make a buck.	[reply]

I disagree. They are the same error message: `Can't modify %s in %s` (see `perldoc perldiag`, search for modify) `chomp` can only modify an lvalue, and neither a 'constant item' nor '<filehandle>' are lvalues, just as dws said. -- 3dan	[reply]
