They come up here at least a few times a year. E.g. https://lists.gnu.org/archive/html/bug-bash/2012-09/msg00072.html > Will funcnest_max be set to non-0 in upstream code in the future? > Or is it just there for the downstream maintainers to set it if they > see it fit? It should be an end-user setting. It can be useful to have the ability to set a limit when testing certain things. I'm sure you're familiar with the age-old controversy surrounding recursion limits in Python. Guido has long argued that the limit makes sense when implementations are not required to support TCO, thus making tail-recursive iteration a "language feature" that programmers can't not depend on. I disagree with Guido, as do many others. Though all the same arguments apply in this case. I see no good reason for an arbitrary limit but I understand the opposing view. -- Dan Douglas
