Brut force:

as this takes some time here's a cheat:
\starttext
\startbuffer[demo]

\stopbuffer
\startTEXpage
\typesetbuffer[demo]
\stopTEXpage
\stoptext
a next run the already prepared buffer will be taken unles it has been
changed.
I thought that this will also be a good usecase of showing Lua+MP
interaction. I wrote the code below following the metafun manual, but I cannot
get it to compile. What am I missing?
You need to put it into the mp namespace:
Thanks. The metafun manual is confusing in this regard and I got
the impression that any lua namespace could be used.
(then eps should be made a linear function of xi)
Oh, I missed that. Thanks.
(and, indeed this is much faster than calculating in MP)
Yes. Iterating over 10^6 values on a 1GHz computer should roughly take
1ms in any reasonable programming language. Metapost for loops work with
macro expansion, which can be very expensive for large loops.
