File.52: Like capturing by reference in lambdas which will be made use of locally, such as passed to algorithms
: a considerably pretentious time period for design or programming model; typically applied Using the (erroneous) implication that there exists a paradigm that is definitely exceptional to all Other individuals.
: a press release inserted right into a software to condition (assert) that one thing ought to usually be genuine at this point in This system.
