I agree itís not what weíre used to seeing as a function call, but
the call-with syntax implies more than that. Whatís being called is a
function object, which also knows its environment, so it has access
to the local variables and those inherited by self at the time of the
function objectís creation. The NewtonScript Language document
describes this far better than I can, but the point is that call-with
is much more powerful than a simple function call so I think the
verbosity is worth it.

Correct. The guidelines say you should make your global function name
unique by appending your developer signature:

DefGlobalFn('|nstrToCstr:MTP|, kNstrToCstrFunc);
...
cstr := |nstrToCstr:MTP|("something");

Not pretty either. I left this out of my original reply because I
thought it would only confuse matters.

Iím sure I speak for most NewtonTalkers when I say I look forward to
reading how you get on with your project!
