[R] Question on closure (lexical scoping) and encapsulation

[Duncan Murdoch]

Coming back to this example:

>> .GlobalEnv
>[1] "$.environment"     "$.foo"             "print.environment"
>[4] "print.foo"         "x"                
>> class(.GlobalEnv)
>[1] "foo"
>> .GlobalEnv$"$.foo"
>function(x,name)get(name,envir=x)

I can't get this to work in 1.0.1.  My "$.foo" method is never being
called, I just get NULL as the result every time.  I can do it using
"[.foo" and .GlobalEnv["$.foo"], but the dollar sign version just
doesn't work.  Any hints?
