runtime crash with "Numeric"

var c:Numeric =233
var b:Numeric =1.0
print c+b

In this simple case it could be detected by the compiler but in the general case it should be handled somehow. If it crashes or throws a runtime exception it means the Numeric type is useless and dangerous.

The plan is to support operator overloading to implement Int + Float and others, in order to get the desired behavior at an acceptable performance level.

Until then, I recommend not using explicitly the Numeric static type if you don't need it, the Numeric limitations should not affect the direct use of Float and Int. You probably already noticed, in the given example simply removing the two :Numeric types will result in the expected static error to be displayed. But if you do need to use Numeric, use it with the Numeric-safe (but slower) methods add, sub, etc.

just curious - is it similar like in Ruby where ```2+3``` is syntactic sugar for ```2.+(3)``` (integer.methodcall+(arg))? In that case I would think it could be easily "redefined" by the programmer as needed? I was also thinking on complex numbers and whatever else might become useful at some point.

thanks for the hint, never knew about the numeric-safe variants.
