We've just enabled warnings as errors in our build system at

Warning: explicit element-wise assignment <exprnew> is better

writeAvail_[0 .. buf.length] = buf;
but this was:
writeAvail_[0 .. buf.length] = buf[];
The type of the involved variables were as trivial as ubyte[]
and in ubyte[] respectively.
What's the idea?

The correct syntax is
writeAvail_[0 .. buf.length] = buf[];
as the other syntax is for assigning a single value to all
elements of the destination array. At least that's how I've
always seen it.
I'm not sure what that warning is talking about though.
