Wish Raising errors or at least warnings if types are not compatible

[b4auser1]

The compiler doesn't raise any errors or at least warnings if types are not compatible (see. sample below)
Problems are discovered during run-time testing. It affects development process performance. If it is possible, please add validation of types incompatibility during compilation process.

Where is the error? Can you add a comment in the code section which shows where the error occurs?

Also, if you attach a project to the post anyone can try it in the IDE and learn from this example.

Lastly, how do you workaround the incompatibility at runtime? Is it possible to check the type?, default to some value, log the error, and carry on...

This issue is fixed in v2.80. The compiler will warn you about incompatible custom types.
