I'm missing what you mean, Bernie.

Here, I tried the following code...

-- abs.e

global procedure abs()
    puts(1, "abs in abs.e\n")
end procedure

abs()

-- end file


-- ns-test2.ex

include abs.e

global procedure abs()
    puts(1, "abs in ns-test2.ex.\n")
end procedure

abs()

-- end file

and it worked without error.

I even went down one more level (created a file with abs that was included by
abs.e) and it still worked as expected.

In fact, the only way to get an error is to not override the function.
