Thank you Alex.
To further clarify, what I am trying to do is create factory methods that
return a common interface. In a nutshell, I am trying to create
constructors that take a common argument.
As it stands, the parameter I specify is very specific (function with a
pointer to a struct):
opts …func(*procStruct)
So end goal is to try to generalize the parameter (if possible), so when I
add more factory functions I can associate them with a particular type
known as plugin.
Also, thanks for the link.. going to take a look.
