Re: Size of @+

[roho]

Just a quick side note. @+ does not interpolate inside double quotes. Printing it inside double quotes results in @+, not its contents. Printing it outside double quotes results in its contents. Feature or bug?

Bug. This is fixed between 5.6.1 and 5.8.0: Compare:

$ perl -e '"foo" =~ /(o)/; print @+,$/'
22
$ perl -e '"foo" =~ /(o)/; print "@+",$/'
@+
$ perl -v
This is perl, v5.6.1 built for i686-linux

..to:

$ perl -e '"foo" =~ /(o)/; print @+,$/'
22
$ perl -e '"foo" =~ /(o)/; print "@+",$/'
2 2
$ perl -v
This is perl, v5.8.0 built for i386-linux-thread-multi
