don't know if it really is advisable, but you can imagine a scenario
where you have different-moded like-named variables within nested
scopes, e.g.:
x = TRUE
local({
x = 0;
local({
x = 'foo';
list(get('x'), get('x', mode='numeric'), get('x',
mode='logical')) }) })
# list('foo', 0, TRUE)
basically, you want, within a scope, the value of a variable named 'x'
from in the closest environment in which it has the given type of value.
