Can I "break out" of an if{} block?

[usenet]

At any point in a loop, I can "break out" of it with a 'last', or I can
"break out" of a subroutine with a 'return'.

Is there a similar way to easily "break out" of an if{} block (without
a goto)?

Thanks!

Sure, just put a loop inside the if block:

if ( $expression ) { {
last if $oops;
} }

Yes, by nesting another if:

if ( $something ) {
# do this always
if ( ! $want_to_last ) { # unless ( $want_to_last ) is "nicer"
# do this when not "lasting"
}
}

Any block (except for the pseudoblocks which are part of if{}, else{},
do{} &c.) is treated as a loop which loops once. So just add another set
of braces and use 'last':

if (1) {{
#...
last if #...
#...
}}
