First time poster, and I was so surprised I was able to find this 
online. I've been working on figuring this out for hours. I've adopted 
the "send(value)" solution and it works great.

My question is, how can I pass arguments to methods called this way? My 
hash is pretty much identical, here's a sample:

commands = {"look" => "doLook"}

I have split the input variable so I can accept more than 1 word at a 
time (input can be anything from ["look"] to ["look", "at", "the", 
"desk"]). I'd like to be able to pass the input variable to these 
methods, but am having difficulty with that. I have tried modifying my 
hash as so:

commands = {"look" => "doLook(input)"}

with no luck. I've also modified my send as so:

send(commands[x](input))

with no luck. Any ideas? Thanks a bunch for any assistance anyone can 
provide :)
