Countability of Source Code
Until recent times, "source code" has always been used as an uncountable noun. More than one set of source code was never referred to as "source codes" but it is being used this way more and more. However, I feel the classic usage is correct; source code is uncountable and should not have a plural form. I tried to change this page to show list the word as uncountable, but I'm not sure of Wiktionary syntax.
