Note that re.IGNORECASE imposes runtime costs (the engine does a function
call every time it looks at a target-string character, to normalize its
case).  Since you only pass uppercase stuff to this, it would run quicker
as:

    cre = re.compile(r'\$(?:([_A-Z]\w*)|\{([_A-Z]\w*)\})') # no IGNORECASE
    return cre.sub(repl, msgid.upper())  # unchanged
