Restoring the magic to the _ filehandle in Perl 5.8.9by clinton (Priest)
|on Jan 27, 2010 at 17:11 UTC||Need Help??|
clinton has asked for the
wisdom of the Perl Monks concerning the following question:
I'm using sub _() as a means to localise text, eg:
The sub looks like this:
The second line of the sub is to handle uses of the special filehandle _ in (eg):
However, perl 5.8.9 has added this warning: Use of -l on filehandle _. So while the other -X functions can handle a glob reference to the special filehandle, -l can't.
The code below, in Perl 5.8.8 and 5.10.9 prints 1\n three times, meaning that it works correctly. However, in 5.8.9, you get the failures listed in the comments.
If I remove the BEGIN block, then both the -l _ and my _() sub work correctly. Similarly, if I load any modules that use -l _ before defining the _() sub, then everything works correctly. However, this is a fragile way of working around the problem - I'd have check any modules that I use for use of lstat.
Is there any way that I can restore the magic to _?
