What is the keyword "incr" in the KDevelop IDE?

Question

I just downloaded KDevelop because it scans header files to offer better suggestions in code completion.
I was looking at all the keywords it suggests when no header files are included at all:
Why is it recommending "incr"?
That's not a C++ keyword.

---

What is it, and what is it used for?
I thought it might be short for increment..?

Answer 1

Probably it's a bug. Looking at KDevelop source, incr has been add for code completion in file languages/cpp/codecompletion/context.cpp on line 2326. It looks like a synonym to increment operation, however only valid synonyms are: and (&&), bitand (&), and_eq (&=), or (||), bitor (|), or_eq (|=), xor (^), xor_eq (^=), not (!), not_eq (!=), compl (~)

Answer 2

I can't see any mention of incr as a keyword or alternative token (such as and for &&) in either C++98 or C++11 so I can only conclude that some other language uses that keyword and KDevelop didn't properly pull in the C++-only keyword set for name suggestions.
