Test that two function variables point to the same function?

Question

How can I test that two function variables point to the same function?

test = lm
test2 = lm

test == lm     # error: comparison (1) is possible only for atomic and list types
test == test2  # error: comparison (1) is possible only for atomic and list types

Answer 1

Try:

identical(test, lm)
identical(test, test2)
