bug.d(6): Error: `TypeInfo` cannot be used with -betterC
It looks like passing an array literal to a function parameter creates a
dependency on `TypeInfo`. It think this has to do with how D is handling the
array literal. It might be trying to allocate it using the GC which is causing
it to depend on GC. You can make the example work if you change bar to the
following:
void bar()
{
static arr = [1, 2, 3];
takeArray(arr);
}
However, I think both versions should work. Otherwise, a better error message
should be in order, i.e.
bug.d(6): dynamic array literals are not supported in betterC. you can fix
this by assigning the array to a static variable instead.
