:-) loud and clear.
Actually, repeat<0,more> forces constant parameters.
I prefer functions because I can have variables as parameters.
This way I can do dynamic iteration. I mentioned that a while
ago in passing. For example when parsing a length prefixed
string from a file. This type of 'dynamic iteration' is invaluable
in cases such as 1) parsing files (even binary files) 2)
resource description, 3) external data representation (e.g. XDR)
including externalisation of objects (persistence) and
