@lunarised Wanted a chunk of memory anyway? We already had that, it was called static arrays.
Seriously, since a couple years I wonder if one can always replace malloc/free with forks.
I think that it should be possible to prove that you always bind memory to processing, and there is no other reason except programmer lazyness to do such processing in the same process.
Counter-argument: sed hold-space processing.
Counter-counter-argument: you just need more expressive pipes and redirections, and instead of one single hold-space, you'd get multiple spaces each connected to simpler version of sed.
Counter-counter-counter argument: that's cheating, as the pipes would handle memory growth under the hood in kernel space.
But... why not?
Userspace programs would be way simpler (and safer) without malloc/free.
Well, to be precise, you'd need to know it at loading time. In mainstream os this mean you must know it at compile time to save such info in your ELF binary or something.
But could we imagine something more flexible than that?
