How to write in D grep not slower than GNU grep?
GNU grep is pretty fast, it's tough to beat it reading one line
at a time. That's because it can play a bit of a trick and do
the initial match ignoring line boundaries and correct line
boundaries later. There's a good discussion in this thread
("Why GNU grep is fast" by Mike Haertel):

Thank you. I understand yet another trick:
$ find . -exec file -bi {} +
is the same
$ file -bi `find .`
