Array of custom type variable / Passing by ref a custom type variable

Hello!
I try to pass an array of custom type variable as a function parameter:
type myType {
int a;
int b;
};
void f(myType t) {
t[0].a=1;
}
At compilation I get the error "Expect ) after [optional] params" on the line of function declaration.
In fact, at start, I wanted to pass a custom type variable by reference.
As it seems it is not possible, my "solution" was I could pass it as an array (as arrays are passed by reference) and then access it by the index "0".

Yep, passing an array of custom type as arg to function is not yet supported. It's in my todo list 
To simulate passing custom types by ref, you can pass the address of the custom type to the function as a nat, and peek/poke or peekw/pokew (depending on the member type) at address+member offset by hand in the function. Not ideal but it should work (I did not test it yet).

Thanks for your reply!
Yes, I thought to do this, but not very readable..
Well, I will use an array of global variable and will pass the index to work with.
