Are you sure?  From what I gather this logic is still flawed.  I mean,
you want to throw if it is *neither* "r" *nor* "R".  So you would need
to express that in your conditions, e.g.

if @char != 'R' && @char != 'r' ...
if ! ( @char == 'R' || @char == 'r' ) ...

(btw, see Morgan's Laws: http://en.wikipedia.org/wiki/De_Morgan's_laws )

Here's an alternative way

raise "..." unless /^r$/i =~ @character

Kind regards

robert
