Hi everyone,
I was trying to get my vector struct to use extensively
references for passing parameters and I found a subtle bug which
make me lose a few hour.
A sample code that shows the bug is here
http://pastebin.com/rvcNdjAE (fails with dmd 2.064 on linux)
I think that the code is wrong and dmd does not recognize it:
opBinary() allocates a struct on the stack which is then accepted
by reference in opOpAssign.
I'd like to know if currently there are correct ways to pass
rvalue structs by reference or if I should pass everything by
value and hope the compiler optimizes all reduntant copies.
