[wellylug] Getting user input into a Perl program

[Cliff Pratt]

I'm probably overlooking the obvious, but is there some way of getting 
user input into a Perl program?

eg, what sort of stuff do I put in the sub 'ask_for_input'? In the case 
below, it would presumbly do something like ask "Continue (Y/N)?" and 
parse the response and return a true value if it gets a negative 
response and would break out of the loop.

while (1) {
	do_stuff() ;
	last if(ask_for_input()) ;
	do_more_stuff() ;
}
