Heh, when writing a state machine the implied loops can be 
nontrivial and then gotos can result in cleaner, tighter and 
faster code than a regular loop with a switch statement or 
function pointers or or whatever. Co-routines and gotos can 
provide pretty clean state machines.

IIRC the minimalistic Beta language used a lower level construct 
which allowed to loop a block (a pattern/object) using a 
"restart" statement. Then higher level looping constructs could 
be built on top of it. Basically like having the "continue" 
statement refer to a block.

Anyway, "for(;;)" is idiomatic in C by now, so changing it would 
be a bad idea.
