    Another place where this can be an issue is in the "edge" construct:

    `define digits(x1) x1
    edge[`digits(10)] // edge[10] or edge[x1] ?
    `define edge(x1) edge[x1]
    `edge(10) // edge[10] or edge[x1] ?

    All of these examples I've given are places where numbers/levels/edges can appear and not identifiers. But, these can also look like identifiers. So, are macro formal arguments replaced at these points? And if so, what if the formal argument identifier is the same as a valid number/level/edge?
