This is essentially equivalent to base::match.call(), but with
experimental handling of primitive functions.
call_standardise(call, env = caller_env())Can be a call or a quosure that wraps a call.
The environment where to find the definition of the
function quoted in call in case call is not wrapped in a
quosure.
A quosure if call is a quosure, a raw call otherwise.
In rlang 0.2.0, lang_standardise() was soft-deprecated and
renamed to call_standardise(). See lifecycle section in call2()
for more about this change.
