ints, the best we can do is 0. With floats, NaN makes it better.
With the logic that NaN is the default for floats, 0 is a very bad
choice for ints. It the worst we could do. Altough I understand that
setting it to something else like -infinity is still not a good choice.
Is it just me but do ints not have infinity values?
in Mathematics yes, but not in D.
I think ints should
default to about half of their capacity (probably negative for signed).
This would be machine depends, as such it should be avoided.
This way you are unlikely to get an off-by-one for an uninitialized values.
something as a Not an Integer NaI should be better.
I think that if D wants people to initialize their variables, it
should generate a compiler error when not doing so, like C# and Java.
For me, having floats defaulting to NaN and ints to zero is somewhere
in the middle... Which isn't good.
I 100% agree.
