Yes, I know this.

How is setting/replacing different from modifying?
e.g.:

Kinda like how strings can be copied and assigned to, but not

If any member variable of a struct is const, then you can't
modify that member ever, and assignment isn't possible unless
you override opAssign so that it overwrites only the mutable

Thanks!
The most obvious way i didn´t think :P

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(,,T.sizeof);
a.__postblit;
/*
output:
POSTBLIT
DTOR

Hi Guys!
In my programm, I have a custom String-type that I want to
initialize some variables of at compile time by casting a string
literal to said custom String type. I thought I could achieve
this straight forwardly, but after trying a bit, I could not find
a (simple) working solution. I

Ok, any chance to switch back and forth between local/remote versions?
