I would like to be able (during development) to draw paths where the points of the path (and maybe thing slike directions) are visualised. E.g. a path where each pair in teh path is also drawn as a dot and maybe teh directions drawn as small arrows.
Does someone have such a beast lying around?

Would Chapter 11, section 11.1 Showing Paths of the MetaPost manual, be
any help here?
Below is a MWE of a random path of curves and straight lines. The points
are shown using drawpoints. The arrow path and control lines are also
shown and are better described in the Metapost manual.
%%%%%%%%%%%%MWE%%%%%%%%%%%
\setuppapersize [A4,landscape]
\starttext
\startMPpage[instance=doublefun]
StartPage;
width := PaperWidth ; height := PaperHeight ; unit := cm ;
path p ;
path pat;
pat := (5cm,5cm);
for a = 1 step 1 until 10:
x:= uniformdeviate(10) +10;
y:= uniformdeviate(10) +10;
if odd a:
pat := pat .. (x*cm,y*cm);
else:
pat := pat -- (x*cm,y*cm);
fi;
draw pat withpen pencircle scaled 5mm withcolor .5green;
endfor;
drawarrowpath pat;
drawpoints pat;
drawcontrollines pat withcolor .625red ;
StopPage;
\stopMPpage
\stoptext
%%%%%%%%%%%%%%% end MWE %%%%%%%%%%%%%%%%%
A better coder than me may be able to incorporate it into what you require.
Best Wishes
