if you are calling a method in a package (?terminology?), and one of your arguments is a variable named $q,$m, or $s, then it ends up being incorrectly highlighted.

If you open up a blank file in kdevelop, an turn on the perl syntax highlighting, none of these lines are 
correctly highlighted
a::a($q, $a);  #this text should be gray (comment colored)
a::a($s, $a);  #this text should be gray (comment colored)
a::a($m, $a);  #this text should be gray (comment colored)

Here are a few things i have noticed:
for the example:
a::a($q, $a);  #this text should be grey (comment colored)

it seems to be treating the $q as a q. it seems to be seeing something like this: q,<text>,. It mishighlights everthing until the next comma, as demonstrated by this example:
a::a($q, $a);  #not gray, #gray


for the examples:
a::a($s, $a);  #this text should be gray (comment colored)
a::a($m, $a);  #this text should be gray (comment colored)
if you add a third space after the semicolon, it will be correctly highlighted:
a::a($m, $a);   #This text is gray
