I understand that your original post was pseudo-code, but aren't you
forced into firing a fixed set of functions {stuff[]} which all use the
same parameters? Seems that set of functions could be rolled into one
which returns a list of values. Or are you also passing in a,b,c,d (with
name-of-function values (strings)) and hoping to slam the function's
return value (int?) back into the corresponding (perhaps out)
parameter? Hm, you could pass in an array of names, iterate over the
array, call the named function and load the return value into a single
declared array, by index, in each iteration of the loop.

Weird!
