in reply to What does ".=" mean?

It's one example of the generalisation of operators like +=: $x OP= $y; is the same as $x = $x OP $y;, where OP can be most of the common binary operators (meaning operators with 2 arguments, one on each side of the operator). So $x .= $y; is the same as $x = $x . $y;

See Assignment Operators in perlop.

[shmem]: that's why it is called "Windows"
[stevieb]: shmem thanks for the 'insight' :P
[shmem]: good thing that Sun already took "OpenWindows", otherwise I'd not stop to shudder imagining an "OpenWindows" from MS
[shmem]: more garbage in, more garbage out that would be
[stevieb]: I found that win10 broke a C# library I was using for one project while enhancing tests for a Perl dist, which breaks other Perl dists, and I'm about to throw my hands up on berrybrew. win2k12 broke one thing, win10 breaks something...
[stevieb]: ...unrelated which requires replacing a lot of code and a whole lib. I'm about to go nix only ffs
[shmem]: stevieb: what you're doing sounds afwully complex. Too much for me this evening to provide brighter insight ;-)
[stevieb]: I don't even own a Windows computer. Both my girl and I have a laptop each with Linux. I'm supporting Windows in some of my projects and I can't even guage whether it's worth it or not.
[stevieb]: shmem It's something I desired to have years ago, which is why I took over berrybrew. Cross-platform build/test automation locally, or over the network Test::BrewBuild
