Triangles. I understand that most of it is very easy, but still a library
will help new users.
Tikz has Tikz-Euclide and Asymptote has a Geometry package. A similar
library for Metafun
will be very useful.

No library that I know of, but drawing tangents (and therefore, perpendiculars) 
is straight-forward:

Circumcircle, orthocenter, etc... are you thinking of triangles or general 
polynomails?

Not sure if it is 'nicer' but I use a table to print addresses onto sticky 
labels. The code should be fairly easy to adapt or just borrow some ideas.

Here's a suggestion:

\definepapersize
  [jeong]
  [width=67mm,
   height=73mm]

\setuppapersize
  [jeong]
  [A4]

\setuppaper
  [nx=3, ny=4,
   dx=4.4mm, dy=1.5mm]

\setuparranging
  [XY]

\setuplayout
  [page]

\setuppagenumbering
  [state=stop]

\setupmakeup
  [standard]
  [align=middle]

\setupblank
  [2*line]

\showframe
\starttext
  \dorecurse{12}{%%
\startstandardmakeup
Text \blank
{\tfd\recurselevel} \blank
Text
\stopstandardmakeup
\page}
\stoptext

That's how I'd approach it. Not sure if it meets all your
requirements, though.

Dear Gavin,

I have managed to create an implementation for these operations which I
think I can convert into functions and put in startMPinclusions and then
use them from. there.

Hi Shiv,

> perpendiculars, circumcircle, orthocenters and such?

I don’t think we have anything like that specifically in the MetaFun world, but 
if there is a MetaPost package you like, you can use it with MetaFun. For 
example, the TeX Live installation includes both ConTeXt and 3dgeom.mp, so you 
should be able to use the 3dgeom package in MetaFun simply with "input 3dgeom" 
in your MetaPost code. (I did a quick check, successfully drawing a drawing a 
cube with 3dgeom. I have not tested it beyond than that.)

If there isn’t a MetaPost package for what you want, Lua may be useful for 
doing the calculations.

Suppose you have a document with a frontmatter of 20 pages in roman

numerals.


So the twelfth page is 'XII', while the twenty-second is '2'.

How do I get 'XII' from 12 and '2' from 22?


try \realpagenumber



The right one would be \userpagenumber, but it works only with the 
current page.


The code for registers does that translation -- from an arbitrary 
realpage of your document to the corresponding user page number, with 
the right formatting -- but I could not find the code that does that in 
strc-reg.* source files.
