Issue Description:

It's possible to change the default types for all literals except array and dictionary

https://developer.apple.com/documentation/swift/swift_standard_library/initialization_with_literals/default_literal_types

Contributor guide

Research direction
Investigate how the default type for literals is currently implemented in the Swift compiler and standard library. Look at the ExpressibleByArrayLiteral and ExpressibleByDictionaryLiteral protocols. Propose a way to allow customization similar to other literal types.
