i would like to see a [sscanf] object....
and a [sprintf] one too.

these are standard functions of C language.

[sprintf] would act like [makefilename], except that accept more than 
one variable (makefilename gives unpredictable results sending lists 
with a format string like a%d_b%d).

so, an example of how [sprintf] should act:

[list foo bar 34(
|
[sprintf %s-%s-%d]

would return a symbol: foo-bar-34
and sscanf would do the inverse job:

[symbol foo-bar-34(
|
[sscanf %s-%s-%d]

would return a list:
symbol foo, symbol bar, float 34


consider this just a request for comment :)
