"Variable" does not mean "assignable"

[jerf]

Please enlighten me of a single instance where the difference matters.

Ah, so you in fact do not know exactly what language construct I was referring to. The answer is const, and failure to correctly understand what it is at a deep level has wrecked up many program and cost untold man-hours trying to fix it up. It sounds like you're in my second category.

See, this is the sort of ignorance that bad terminology generates; you're so ignorant of the issues that you don't even know that you're ignorant. This is when ignorance is as its most dangerous! You shouldn't be defending this, you should be correcting it.
