Subject: Need cohercing a var into a method name

Hello,

I need a small bit of help, I am playing with Logger class and ran into a small problem I am not sure how to solve.  Namely, I was interested in command line setting of the logging level, however, the passed argument is not accepted as a method name nor can I figure out how to get the arg "coherced" to a string prior to evaluation of the method call.  Here is my code:

  when "--debug"
       if(DEBUG_LEVELS.include?(arg))
         mylog.level = Logger::arg.to_s
                              ^^^^^^^^^^^^
       else
         puts " "Debug level can be one of DEBUG, INFO, WARN, ERROR, or FATAL."
      .....
(hi-lited is the code segment in question)
I am using GetoptLong to do the cmd line processing.  The error given by ruby is:
test.rb:136 undefined method `arg' for Logger:Class (NoMethodError)
...

TIA,
Phy
