But the same man page also describes "eval" like this:
'eval' evaluates the 'expr' argument
Part of the confusion actually comes from the overspecificity of the
documentation. When the actual majority of the verbiage in a manual page is
given to how a function "evaluates" its argument, one tends to infer (by
the flouting of Grice's maxim of quantity) that this term "evaluation"
refers to

implemented, but is nonsense from the R user's standpoint,

R-team,
The $value element of the return value of *withVisible* does not agree with
the return value of *eval* when *withVisible* is passed a variable (symbol)
containing an expression object or anonymous code/expressions which
generates an expression object when evaluated (such as calls to *parse
