Problem solved partially.

in structs I use fix length arrays declarations, and alias its to
structs, but not allowed casting to fix length arrays.
I want check array length in compile time
auto opBinary(string op,E)( E[DLen] b ) // fix length array

This would have to be implemented very carefully. There are enough
hard to reproduce symbol resolution

If you have strong feelings about this, then add a Bugzilla entry.

Probably. It's an easy mistake to make. Maybe the compiler
should issue a warning when opAssign attempts and fails and
opOpBinary is defined.
