• Forgetting that user-defined literal suffixes can be associated with both raw and cooked literal operators, and the compiler chooses based on the context and available overloads.
• Assuming that the order of user-defined literal application is predictable in all cases.
• Forgetting that user-defined literal suffixes can be a valuable tool for creating more readable and maintainable code when dealing with domain-specific literals.
• Using incorrect escape sequences in character or string literals.
• How do literals interact with template function instantiation?
• Are 'true' and 'false' keywords or literals?
• Assuming that literal operators can be used to create literals with custom security properties or encryption at compile time (though this would typically involve more complex mechanisms).
• Can you use literals as default arguments for function parameters?
