Steffen,
if you fear performance bottlenecks, did you consider using a Stream as
a single block parameter?
Your requirement sounds a bit as if you do some diving into a structure
(recursion?) where "someone" (maybe even conditionally) adds another
argument before the block is evaluated. I've had good results in both
performance and readability with Streams in such scenarios...
Just an idea, maybe completely useless...

Steffen,
My first response, is do NOT optimize too early. The performance
bottlenecks are not always where we think they are.
In Pharo you can add methods to BlockClosure class. You can go up to
255 arguments IIRC.
But, of course there is no primitive to handle them, so you endup
writing the same code.
Better use |valueWithArguments:|
|block valueWithArguments: (multipleArgs copyWith: singleArg)|

Hi!
I want to evaluate a block an argument 'arg1' and additional n
arguments
given in an array 'args'. The following code does the trick:
block valueWithArguments: (Array with: arg1) , args.
Is there a way to do this without the overhead of creating a new
Array?
(How) Can I add additional #value:value:[...] methods to
BlockClosure that
evaluate the block with n arguments directly without falling back to
#valueWithArguments: ? If yes, what's the maximum?
Cheers!
Steffen
