I need a feature, which create a new temp dir, as does
tmpdir = Dir.mktmpdir("some_prefix") in Ruby, but it seem like this not feature available in Crystal.
Then, i notice that the name of following two api really confusing.
I suggest that we should give a clear name, e.g.
|Old name||New name||Feature|
|File.tempfile||File.mk_tempfile||Create a temp file|
|not available||Dir.mk_tempdir||Create a temp dir|
|Dir.tempdir||Dir.tempdir||Get temp dir name|
