It is posible that single quotes have more priority than double qutoes while 
debuged, everything inside single quotes gets procesed earlier than defs 
inside double quotes. But I doubt you can notice speed diference if the same 
script does not use double qutese anywhere else. But if combined, single 
quted gat the precedence.
This is, however, only my best guess.
