... I've been thinking about this for a little while, but, would any of you
find it useful to have ruby be able to provide you with the source of a
function ...

I could see a number of uses. Including being able to modify the function a=
t
run time, or to be able to see the parameter list ... or other things.


Anyways, I was thinking of something like:


func_body =3D Object.method( :to_s ).src

func_body.replace( "\* 3", "\* 4" )

Object.class_eval( func_body )

... what do you think?

You already can do that with ruby2c and ZenHacks.

MetaRuby is rewriting Ruby in itself. When we're done you can get
the source for Object#to_s, but we haven't gotten that far yet.

Yep, that's the second link to the Zen stuff ...

I went and looked at things, looks like what I'm after ...

Thanks all.
