With regards to complexity theory, I'm inclined to assume that syntax is a constant factor in the equation. You only have to extend the language by writing a macroprocessor once, if you count that to the power of the language. That's why C is still very powerful, although other langs have half an STD-Lib toolbox hidden in syntactic sugar.
