When reading this:
Does the symbol(red color above) mean user-defined function here?When a user-defined function is evaluated, the context is switched to the parent context of the symbol it is called with.
If there are context A and B, B has a user-defined function myfun
in A context, I write code to call myfun of B context, and what will happen?
word "parent context" only occures once in your manual, I do not know what dows it mean.
caller's context?
