Dir.entries() returns both "." and ".." in its results

[docelic]

Calling Dir.entries() returns both "." and ".." in the result set, and there is no sort order defined.

This essentially makes one have to call:

result= Dir.entries( "/some/dir")
result.delete "."
result.delete ".."

Before the results become usable.

Is this intended behavior and/or there's room for improvement?

[makenowjust]

Dir.entries uses C's readdir function internally, and readdir yields both "." and ".." also, so Dir.entries result contains them. In addition, this behavior is same as Ruby's 'Dir.entries'. I think this is intended behavior.

[straight-shoota]

Ruby has also Dir.children for exactly this purpose. It would make sense to have this in Crystal too.
