It would be nice if integer constants were able to resolve their type:

3 -> ShortInt
180 -> SmallInt
etc etc.

This would be good for:
   b: Byte;
   i := b + 500;

this code creates "i: Byte;" in r50230.
I still think it is better than the behavior before r50230 that created 
"i: Integer;" for:

   b: Byte;
   i := b + 1;

Because adding a constant out of the bounds of one operand is much less 
common than within its bounds (IMO).

Yes, whatever: single, double, extended, glFloat - maybe create an IDE 
option for default integer/float/string/boolean types? The user then can 
decide what precision he wants to use by default. Do you think it is 

The integer predefined setting should be preferred to the resolved type 
in case there is no well-defined variable. E.g.:
i := 10 + 5;
Should create the user-defined default integer type ("i: integer" by 
default) and not "i: Byte".
