the problem with vladimir's functions is the disclaimer.
he wants some reward if you use it commercially. so i didn't include it.
and it does more than is needed.

I'll have a look also and maybe rewrite it :)
it uses xrecords and is modifying instead of your simple query functions.

I will not rename the dict module for sure. this is pretty stable now.

Thanks. I'll think about the name conflict. maybe a check-function
which tests against vladimir's function.
maybe the put function as well, but probably in a later release (past 1.0)
I see no big advantage over xdata.

of course the encoder/decoder is very useful. I'll probably add serge volkov's
or my private version to the stdlib sooner or later.
mine is not recursive.

yes, I'll remove it.

sure! there're still some known problems but not discouraging ones.
and there are still some not yet known problems for sure. just last week
I found a bug in vl-file-copy! (which is fixed in the std- version 0.5004).
today I fixed STD-GET-DRIVE-LIST
