if(AA) <-- invalid

char[][char[]] k;
if (k) // this code should be invalid, cause it could strongly be a typo or some porting mistake from some
C source

I hope if(identifier) only work for Bool & Pointer types

For an AA, I believe this works out to length - the length of the char[][] keys;

if(k) I believe checks k.keys.length by virtue of being at *(&k), which is 0 until you assign it a buffer.  This seems like the right behavior to me for an AA.

if(k) asks if k is a non-empty Associative Array.

no if(k) doesn't indicate an empty AA, it just tests whether it has ever been used.
if k has been used and then cleared, still if(k) test would pass
