Calling copyctor manually

[SrMordred via Digitalmars-d-learn]

Its possible to call copyctor manually without calling dtor?
ex, what i did before:

struct T{ ~this(){ writeln("DTOR"); } this(this){ 
writeln("POSTBLIT"); } }

T a;
T b;

memcpy(&a,&b,T.sizeof);
a.__postblit;

/*
output:
POSTBLIT
DTOR
DTOR
*/

With copy ctors, not sure what to do.


struct T{
~this(){ writeln("DTOR"); }   
this(ref return scope T self){ writeln("COPYCTOR"); } }

T a;
T b;

memcpy(&a,&b,T.sizeof);
a.opAssign(b); //???
//same as a = b;

/*
output:
COPYCTOR
DTOR
DTOR
DTOR
*/

I want something like '.__xcopyctor'
