This one is not in Guix, so I'll replace it by node-mersenne.

Let's try not doing anything special:

$ guix shell node-mersenne node
$ node
> mersenne = require('mersenne')
{
  MersenneTwister19937: [Function:think we need documentati 
MersenneTwister19937],
  rand: [Function (anonymous)],
  seed: [Function (anonymous)],
  seed_array: [Function (anonymous)]
}
> mersenne.MersenneTwister19937
[Function: MersenneTwister19937]

No setup appears to be required beyond simply installing node and the 
node library and using node's 'require' function, so I don't think we 
need documentation for this in Guix (I'm assuming that node documents 
'require'), though I suppose we could have it for completeness  (*).  If 
doing that is considered a good thing, it seems to me that it should 
then also be done for Guile, Python, C/C++/etc, Minetest, Vim, ...

Greetings,
Maxime.

(*) E.g., when looking for the 'require' function, there was initially 
some slight confusion with 'require' accepting relative and absolute 
file names so I was fearing it might need to be passed 
$GUIX_ENVIRONMENT/lib/node_modules, but this turned out to be unfounded.
