In addition to the points other folks have made, I should point out
that using & to call subroutines is a bad idea, unless you know
exactly what it does and you really want to do that. The normal "best
practice" way to write the above would be:
if ( ask('Do you want to do this?') ) {
# do stuff
}
For details, have a look at "perldoc perlsub", especially the
"Prototypes" section.
