0107: Expected function return type

Compiler expected a valid identifier to follow a colon (:) in the function signature but found something else.

E.g. consider this example:

function bar():

The function definition ends with a colon implying a return type, but there is none defined. Or:

function bar(): 5

Compiler found an integer literal, where a name of the type was expected.

Possible solutions:

• add one of the known types after the colon:

function bar(): int

• if function returns nothing, delete : after arguments list

function bar()
