Is changing the function calls just a matter of style, or is
there a more important reason to do it?

Use 'or' and 'and' to remove clutter, they have different precedance and
are often useful in this c
string.

Shaun,
You would want to use a switch (sometimes called "case") statementtry
something like this
MYSWITCH: for ($something) {
/string0/&& do {
&do_something;
last MYSWITCH;
};
/string1/&& do {
&do_something;

if (($something eq 'string0') || ($something eq 'string1') || ($something =~
/string2/)) {
&do_something;
} else {
&do_somthing_else;
}
