Subject: Re: split doesn't work

Sora's suggestion works, but doesn't explain what is going on. The
reason is that the variable (@def) is a string the first time around,
but after the first split it becomes an array because that's what
split returns. You can convert it back to a string after the shift
with to_s or join, like so:

definition = definition.to_s

or

definition = definition.join(' ')

Adding a '=' essential calls to_s on the array.

By the way, def is a reserved keyword, I would avoid using it as a
variable name, especially since there are better choices.

HTH,
Ammar
