templates and when defined

[Pixeye]

A pretty simple question but I guess It's better to know for sure:
    
    
    template check_error_remove_component*(this: ent, id: uint16): untyped =
        when defined(debug):
    
    
    Run

If I define debug the check_error_remove_component will be ignored, but I still 
trigger check_error_remove_component from the code, so it will be executed and 
it will pass variables to nowhere or it will be ignored completely?
