Issue ID: 19907
Summary: passing slice to fixed array not working with variable
offset
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P1

Consider this function:
void fun(ref char[4]);
You can call it like this:
char[20] buffer;
// pass a slice of buffer as the static array
fun(buffer[10 .. 10 + 4]);
That works as expected, but this doesn't work:
// pass a slice of buffer as the static array with variable offset
int x = 10;
fun(buffer[x .. x + 4]);
This is pretty annoying... only workaround some hideous casting:
fun(*cast(char[4]*)(buffer.ptr + x));
Would be nice for the prior expression to work in @safe code.
