Because the code block is missing a space after the opening brace; the 
opening brace is ignored, but the following closing brace is parsed as 
the end for the tfunc function code block.

The following statements are executed for the global scope since the 
function definition block is closed by the faulty syntax above.

The bug is in your code.

spot such syntax errors.
