Enables monkey's Strict syntax mode.
By default, Monkey allows you to take certain shortcuts when programming. However, Monkey also offers a special Strict mode for programmers who prefer a stricter language definition.
The differences between the Strict and non-Strict modes are:
- You must always specify the type of all variables, function return values and function parameters.
- All function call parameters must be enclosed in brackets.
- A function that does not return Void must end with a Return statement.
- Variable type, function return type and function parameter types can be optionally omitted. In this case they will default to Int.
- Return statements can be omitted at the end of a function. In this case, a Return statement will be automatically generated that will return an appropriate default value for the function type. That is, False for bool, 0 for int and float, "" for string,  for arrays and Null for objects.
- The brackets around function call parameters are optional if the function is being used as a statement, or if the function can be called with no parameters.
While syntax is shown in Strict mode, the examples in this documentation will normally be presented in non-Strict form.
' In Strict mode...
' the :Int type definition is compulsory...
"Strict mode is...different!"
' all function calls require brackets...
' and we MUST return a value.
' Non-Strict version of first example, declaring no Return
' type, no brackets for Print statement and no Return value.
"Non-Strict mode is...forgiving!"
