Description

Hello all. I couldn't remember if this had been requested before or not but...

It would be kind to be able to do:
current_ruby = OS.ruby_bin
system("#{current_ruby} another_file.rb")

And thus guarantee execution of a sub-file using the same ruby executable.

Today we have
system("#{Gem.ruby} another_file.rb")

but I'd like to have something available without loading full rubygems.

Python equivalent: sys.executable

Suggestion:

OS.ruby_bin # or OS.executable, etc.
=> "C:/installs/Ruby193p194/bin/ruby.exe"
or
RbConfig.???
=> "C:/installs/Ruby193p194/bin/ruby.exe"

Thanks.
