Casting char[] ranges to string can lead to unexpected behavior

[Domingo via Digitalmars-d-learn]

I spent two days to find a nasty aleatory problem due to a string 
been assigned a range from a char[] array.

This issue on vibe.d detail it a bit more:

I'm putting it here to call attention for other developers for 
this problem.

Cheers !
