Summary
This article examines the performance implications and design considerations of closures in C and C++ programming languages. The author discusses how closures (programming constructs that bundle data with instructions) can have significant performance costs depending on their implementation design. The article analyzes various extension designs for C and C++ closures, highlighting that many current and potential designs are suboptimal from a performance perspective. It serves as a technical deep dive into programming language design trade-offs for closure implementations.
Key quotes
· 3 pulledI had a vague idea that closures could have a variety of performance implications; I did not believe that so many of the chosen and potential designs for C and C++ extensions ones, however, were so… suboptimal.
Closures in this instance are programming language constructs that include data alongside instructions that are not directly related to their input (arguments) and their results (return values).
But, before we get into how these things perform and what the cost of their designs are, we need to talk about what Closures are.
