I use the @ decorator to behave exactly like a c macro that 
does have fewer side effects. 

I am wondering is there other interesting methods to do the 
jobs in Python?

A lot people complained that no macro in Python. 

Cheers to the rule of Python :
If there's none then just go ahead and  build one!
