I noticed tonight that the jot (∘, Compose) operator is only indirectly mentioned in GNU APL ]HELP. Unlike most core APL symbols GNU APL doesn't output anything for ]HELP ∘
However, looking at the source code it appears that this pseudo-operator doesn't really fall into any of the classes supported by the definition file syntax. 'Jot' is really sort of weird and in a class of its own.
I had hoped to provide a trivial patch to resolve this, as I have done recently for the ]HELP text of some other operators but am unsure how to proceed. It seems inappropriate to introduce a new 'arity' argument to the macro used to generate entries ...
At the very least, would it make sense to redirect ]HELP ∘ to ]HELP . (perhaps even via code instead of whatever is auto-generated by the .def files) since it mentions a common usage of 'jot' there?
