One possible use for a "begin ... end" statement is for implementing the "do ... while" loop in C, where a loop is
guaranteed to run at least once.

x=0
begin
  x+=1
end while x<5

Other than that, a "begin ... end" statement standing alone is probably useless.

In the code for Font_Test that's a rather poor use of classes, and the "begin ... end" statement certainly wasn't used to create a loop, as I mentioned above.  The following would look better:

module Font_Test
    Font.default_name = "Rod"
    Font.default_size = 15
end

But even with this, a module is useless without methods in any case.

Don't say it's a poor fix if it works a 100% of the time with no bugs. Thanks poccil I didn't know "begin" could be used in conjuction with a 'while'. I should have known Ruby had more ways of looping.

"Thanks poccil I didn't know "begin" could be used in conjuction with a 'while'. I should have known Ruby had more ways of looping."

eh, maybe if you take a look at Main you'd notice that it includes a begin and a while already...
edit:
mmm on the same level, interesting...

Rofl don't make fun. That while is within the loop. The while loop he created was by placing the while on the same line as the end. Kind of like a do while loop in C.
