[Rd] Possible bug in 'new()' for Reference Classes

Dear list,
I think I stumbled across a little bug with respect to the standard
initialization routine for Reference Classes.
It seems that a field 'self' is treated as if it's name would be '.self'
(which we know is reserved for the self reference of the instantiated
object itself) and thus an error is thrown.
If the field value is assigned in an explicit call after the
instantiation via 'new()', everything works just fine:
setRefClass("ClassInfo",
fields=list(
self="character", super="character", sub="character"
)
)
new("ClassInfo", self="B", super="A", sub="C") # Error
x <- new("ClassInfo", super="A", sub="C")
x
x$self <- "B" # Works
x
Best regards,
Janko
