Just wanted to mention that GNU C has supported nested functions since forever, it's one of the main reasons I prefer GCC over Clang these days.

  Yes and it annoys me no end that clang has refused to implement them as well, as they were part of my codebase as well... How better to implement stuff like qsort() callbacks than with a simple, contextual small function just over it ?? YES it is dangerous due to stacks etc etc but hey, we're grown up adults, not script kiddies.

    Clang has Blocks instead of nested functions. There may be patches for gcc-4.2 for Blocks but they didn't make it to the mainline. https://en.wikipedia.org/wiki/Blocks_(C_language_extension) https://en.wikipedia.org/wiki/Blocks_(C_language_extension)

      Using a chainsaw without paying attention is how fingers are cut off, using that as an argument against making chainsaws easier to use doesn't make any kind of sense.
      • pjmlp 8y ago
        Good chainsaws have protection mechanisms builtin. C does not.
        • bgongfu 8y ago
          Good for you maybe, projecting that on people who have a clue what they're doing doesn't make sense either. They're mostly messing up chainsaws as well these days, for the same misguided reasons.
