It seems to me that the only type held by a '&' variable is treated as
the container type. And, the value type in such a declaration is
uniformly used as a function return type. Is that correct?
So if the most basic declaration is
my Int &func;
means that whatever function this refers to will return an Int, but
my &func1 is Routine;
my &func2 is dotNETwrapper;
describes the "container object", which must have the Callable role. I
could then not assign a simple Block to &func1, for example.
Is that right and all correct?
So, how do you access the container object?
either of those? something different?
