Because there is a tradeoff between type inference and overloading. Operators 
are conventionally heavily overloaded (e.g. in maths) and having overloaded 
operators works well. Allowing all functions to be overloaded weakens 
inference more and doesn't buy you so much, so you must choose to draw the 
line somewhere.

I would like to have "sin" work on float and float32 in F# though... :-)
