What is the proper way to take a char* value (passed from C code) and 
create a dynamic array from it?  Is it possible to do this without 
making a copy?  You could copy it by hand, element by element, but 
there's got to be a better way (perhaps a cast from char* to char[] 
would set both the buffer and the length to the right size?).  I checked 
the D spec, and I can't see any reference to it.

Array slicing syntax does the job:

char *foo();
char *p = foo();
char[] b = p[0 .. strlen(p)];

I should add this to the spec.

Better yet, add another function to string.d.
Could be toString(char*).
