int hex = colour_to_hex(10);
However,
|colour_to_hex((enum colour)10)
compiles as C under the above option without warnings,
while compiling it as C++ one gets:
|warning: The value '10' provided to the cast expression is not in the valid range of values for 'colour' [clang-analyzer-optin.core.EnumCastOutOfRange]
|warning: the result of the conversion is unspecified because '10' is outside the range of type 'colour' [-Wconversion]
