Subject: [ruby-talk:9460] reading an entire file as a string

[This is something i've been wanting to ask for a while.]

What is the reason we only have IO.readlines and not IO.read?

Is File.new("data").read then the recommended way of reading the entire
contents of a file as a string?  Unlike the IO methods this does not
automatically close the file object.

The resultant file object is closed when garbage collected.  I was wondering
if before the GC happens, whether lingering file objects would cause the
maximum number of allowed open files per process to be exceeded. Ran
File.new on a bunch of unique files in a tight loop and interestingly ruby
seems to kick in the GC when it fails to get a file handle from the OS ?
