I wonder how these compare to high frequency training standards. It seems like they'd have similar speed/reliability/predictability requirements in the critical paths.

JFS-CPP bans exceptions because you would lose control over the execution of the problem. The HFT crowds didn't like it because you'd add 10ns to a function call.

At least before we had zero-cost exceptions. These days, I suspect the HFT crowd is back to counting microseconds or milliseconds as trades are being done smarter, not faster.
