I've got a Ruby trivia question:

Copy code

require 'mkmf'
CONFIG['MKMF_VERBOSE'] = "1"
create_makefile 'qsort'

The code works and generates a Makefile. The content is as intended

Copy code

# V=0 quiet, V=1 verbose.  other values don't work.
V = 0

I do not understand scope. From my understanding

CONFIG

is a local variable in the main script. How can that possibly be visible in the function

create_makefile
