Both "123." and "123.E123" is valid C. For some reason, D only
copied the former.
It's to support UFCS (Universal Function Call Syntax). The idea
with C compatible aspects of D is to not *silently* break code
when there's a different meaning for it. And so, these generate
an error message in D (although the error message could be much
better).
It could silently break code if the right function is defined.
The following example is valid in C and D (except
import/include), but prints a different value:
```D
// #include <stdio.h>
import core.stdc.stdio;
int E2(int i)
{
return i;
}
int main()
{
float f = 123.E2;
printf("%f\n", f);
return 0;
}
```
