TBH, this is the fault of the English language :-). The words that Qt
uses for its API are more intuitive to English speakers, if less
consistent. The words STL uses are more logical┬╣ and consistent, but
less intuitive.

I've never actually stopped to think about STL being logical┬╣; every
time I use it, it drives me nuts because the API is not "natural".

(┬╣ In the sense of "strictly conforming to formal logic".)

Consider... if I ask you what relation the letter 'A' has to the
alphabet, is it the letter *at the front*, or is it the *first* letter?
I bet you, and most (native, certainly) English speakers said it's the
*first* letter. STL's word choices are... a bit like writing code in
King James' English.


I do however feel that Qt's consistent use of verbs for actions and
non-verbs for properties (i.e. empty vs. isEmpty/is_empty) is far superior.
