"Compilation time" - of course not that objective as heavily 
implementation specific but still an indicator for the complexity of the 
language :)

But seriously: from my own work on an ES4 interpreter (based on the 
previous draft back then) I saw the biggest impact on the implementation 
to be in the "compilation phase". This went hand in the hand with the 
*advantages* of the type system, i.e. the possibility to apply 
optimizations before execution.

In my personal book I therefore judge the complexity of a language also 
based on the observation whether runtime implementations typically include 
a compiler, i.e. offer an eval() function or not.
