ok. Thank you!

Ah, the residuum is something I know :)

Sounds great!

Best wishes,

You might want to look at 'squeeze-syntax-object' in
ice-9/compile-psyntax.scm, which we use to reduce the size of
psyntax-pp.scm.  Unfortunately, this breaks 'datum->syntax' in the
general case.

I would like to be able to access Javascript functions from Scheme,
possibly with a (system foreign) type API, but this is not a priority
at the moment. Getting as much of Scheme as possible working is the
main thing. On my list, you could put it as the unspoken 5th stage.


As for residualisation, it's not a technical term. More accurate
terminology would be serialisation of syntax objects. Maybe you can
interpret my use of "residue", as being partly negative, as residue is
something left over at the end of a process. Syntax objects are quite
big, (in one experiment I did today, it was half the size of the
output) and if possible, I'd like to avoid emitting them, where
possible, since this is going to be sent over the network.

That sounds great!

Is there already a clean way to run javascript functions from scheme —
for example accessing the DOM? That would directly allow pure Guile web
development.

What does residualization of macros mean? (I feel I’m missing language here).
