1: There should be a warning when a numeric comparator has as one of its
sides a constant string.
2: There should be a warning when a reference is used in a boolean context.
Examples, based on what I saw today in the wild:
if ($array_reference){
if ($dispatch_flag == 'green'){
handle_green_case($array_reference)
}elsif ($dispatch_flag == 'blue'){
handle_green_case($array_reference)
}else {
neither_blue_nor_green($array_reference)
}
}else{
warn "it's empty!"
}
For extra extra points #1 could upgrade to a string comparator, but that
might be too much DWIM.
