Parallel make for perlbrew

If you've ever built Perl from scratch, you probably know how much faster it can be to make and test in parallel. On the other hand, if you use perlbrew on a multi-core processor, you probably already figured out that it wasn't using all your processors. I was very pleased to discover an undocumented '-j' […]

Patching the Perl core for lazy file handle objects

Last night I was inspired to patch the Perl core to load IO::File on demand when calling a method on a file handle would otherwise die. This effectively makes file handles actual "lazy" IO::File objects. If you want to use file handles procedurally, you never need IO::File. But if you try to treat handles as […]
