There isn't a syntactical element in Perl to do case statements (aka
switch in C/C++ & Java). However, they can be done in a variety of ways:
use the Switch.pm module
or use the aliasing for does into $_:
SWITCH: for($somevar) {
/value1/ && do {
...
last SWITCH;
};
/value2/ && do {
...
last SWITCH;
};
...
die "Invalid value $somevar\n";
}
There are many ways to do this in Perl, which is one of the reasons given
for not having an explicit switch operator.
