Thanks to you both for the information - that's exactly the level of
detail I was looking for. I ask because I want to play around with a
function to automatically cache expensive operations to disk, in a way
that can be lazy loaded on the next run.

A follow-up on this.
Cygwin has recently[*] added support for C99 complex math, taken from
NetBSD with code that is very similar to that from Steven Moshier
available via http://www.moshier.net/c9x_readme.html.
That code isn't entirely right, especially not at the cuts on the
inverse functio

Also, if it it adds any value to what you are looking for, the output
of serialize() also has header information, cf. R-devel thread 'Small
inconsistency in serialize() between R versions and implications on
digest()' started March 7, 2007:

See the R-internals manual: there is more info in the R-devel version,
not least because saveRDS() is added to the mix.
But basically serialize() and sav

This is because there is an as.list.function, but your classed object
does not inherit from 'function'.
However, I think coercing to a list is S-like, and in R we have
formals() and body(), and I think you want the former.
Seems this was a late 2008 change: maybe the author can tell us why it
For this application I would use names(formals(object)) to extract the
formal arguments.
