Re: Can I "prune" directories with walkDirRect?

[HVN]

I was asking the same question on IRC and just found this. Come from Python, I 
tried my first Nim program by convert existing script which scans a directory 
of 300k files to filter out 25k files. The Nim version would takes ~ 17s to 
run, as it scans all the directories while using find -prune or python os.walk 
and remove excluded dirs from dirs, which run in 1s. This would be really great 
feature to have in stdlib.
