Ahh, so there goes the idea of just using heuristics (i.e. am I looking
at a string of digits only) to determine if it's a port number or a
container name.

Makes sense.  So that explains why not another character such as /.  I
suppose # might work as a delimiter for specifying a port number:

e.g.
	foo#portno

I seem to recall seeing that in BIND:

You might need to escape the # in some places, but it would at least
allow specification of the port number.
