Error passing arguments to embedded functions

When passing arguments to embedded functions, there is a conflict between argument names and unrelated attributes with the same name but different capitalization.

For example, the following runs successfully:

    IMPORT Python3 AS Python;

    anyinput := 5;

    UNSIGNED testFunc(UNSIGNED anyinput) := EMBED(Python)

        return anyinput + 1

    ENDEMBED;

    result := testFunc(1)

    OUTPUT(result);

But if I change the second line from:

    anyinput := 5;

to:

    anyInput := 5;

That is, change the capitaliztion of the attribute by 1 or more characters, the job fails with the following error:

Error: 0: pyembed name 'anyinput' is not defined

This attribute should be independent of the argument name for the embed, but there is some errant interaction when the capitalization is changed.
