Properties containing functions aren't replaced like numbers and other data types

[guiprav]

• OS: Debian 9.
• Node version: 6.3.1.
• Library version: 3.0.0.

Why should properties containing functions behave differently from, say, numbers?

• Consider: mergeDeep({ a: () => 1, b: () => 2 }, { b: () => 3, c: () => 4 }).b()
• Expected: 3
• Got: 2

vs.

• Consider: mergeDeep({ a: 1, b: 2 }, { b: 3, c: 4 }).b
• Expected: 3
• Got: 3

Should the title say something about "expected result?" or do you want to show where specifically the code is "handling something" improperly?

Was the comparison between the behavior of a property containing a function vs a number unclear?
