[erlang-questions] Intrusive function intercept

[Tyron Zerafa]

First - I do not want to clutter my code with *do_something(); *I need this
perform this call multiple times at different places.
Second -* do_something()* performs some access control logic, *test() *is
any other function accessing resources. Ideally, developers writing
*test()*functions wouldn't have to worry about access control (this
should be
hidden).
