In general the operations in memory are very fast, so even on high load
you will barely notice any impact no mater the variant you try to use.
For sake of completion and showing alternatives, you can use regexp to
see if # is in the value or not:
if($var(a) =~ "#") {
# - the char # is inside $var(a)
...
} else {
...
}
