Subject: Catching undefined global variable errors

Hello everyone,

have a look the following surprising code:

$the_key = "ley1" # a common orthographic error

a = { "key1" => 1, "key2" => 2}

unless a[$the_key]
# ruby doesnt catch this error
puts "SURPRISE!!"
end

Is there a way to catch such orthographic errors (and save
valueable debugging time)? I expected that the interpreter
would raise an Exception (undefined global or something) for
this code.

best regards,
George Moschovitis
