And that's my bottom line. The term can only be understood to mean its intended meaning, if you have previously encountered it and have rote learnt to interpret that particular combination of those two words, when used in the specifications for a computer language, to mean that intended meaning. There is no way to arrive at that interpretation through logical analysis of the juxtaposition of the two words themselves. Even in context.

Which is basically the definition of an idiom. Most natural languages would be poorer if we discarded every expression (idiom) that matches your description.
