Gives error: Error: e2ir: cannot cast lal of type nagger* to type ubyte[]
I have bad knowledge about this and don't understand why I cant do this :(
What I really want is an array of naggers and save them binary to a file :)
This was like my step 1, and it failed miserably...

Thanks for help.


Structs are not castable to arrays directly. You can achieve what you 
want like this (untested, but should work).

(cast(void*)&lal)[0..nagger.sizeof];
