Sigilante

An agent is going to route through `++on-fail`. Offhand I think you'd have to test whatever state change or result that `++on-fail` produces.

We _could_ jet parts of this, but the odds of getting a jet mismatch are fairly high on the transcendental functions. Maybe if we stuck to the same algorithm. This...

Should also add doccord comments to every function.

I guess link it into `%base` too (or maybe `%landscape` once we have it).

This defines the following arms in h/s/d/q: ``` ++ tau .6.2831855 ++ pi .3.1415927 ++ e .2.7182817 ++ phi .1.618034 ++ sqt2 .1.4142135 ++ invsqt2 .70710677 ++ log2 .0.6931472 ++...

Need to add rounding stuff

It's pending `++round` fix (on FP rounding in bits) and duplication to other cores. Otherwise G2G.

Superseded by #7000.

Resolves #1471. Now you can trip, then head, then increment the value. Before you had to trip the value, then head that, then increment that. (Just offers a different intuitive...

It's catching on the parser for `;.` so I'll have to debug.
