[Discuss] confusing on name/usage of File.tempfile and Dir.tempdir

[zw963]

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.

def self.tempfile(suffix : String | Nil = nil, *, dir : String = Dir.tempdir, encoding = nil, invalid = nil)

Creates a temporary file.

tempfile = File.tempfile("foo", ".bar")
tempfile.delete

def self.tempdir : String

Returns the tmp dir used for tempfile.

Dir.tempdir # => "/tmp"

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

I like the proposed re-naming, but fear it would break things. So, it might take some care to implement.
