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;
}
```
