[Rd] making object.size() more meaningful on environments?

[Hervé Pagès]

Hi,

Currently object.size() is not very useful on environments as it always
returns 56 bytes, no matter how big the environment is:

   env1 <- new.env()
   object.size(env1)  # 56 bytes

   env2 <- new.env(hash=TRUE, size=75000000L)
   object.size(env2)  # 56 bytes

   env3 <- list2env(list(a=runif(25000000), L=LETTERS))
   object.size(env3)  # 56 bytes

This makes it pretty useless on reference class instances and other
objects that use environments internally for caching or other purposes.

What about changing this and make it return something more meaningful?

Cheers,
H.
