I'm still getting the std.regex errors. The offending uses of writef/writefln are all inside the 'printProgram' function that starts at line 1161.

This worked on 2.055, but the 2.056 beta gives "dupImmutable.d(9): Error: cannot implicitly convert element type immutable(Bar) to mutable in iarr.dup":

struct Bar
{
    int[] b;
}

void main()
{
    immutable Bar[] iarr = [];
    Bar[] arr = iarr.dup;
}

I *think* that's a bugfix (6695 maybe?) and not a regression, but I wanted to double-check.

Yeah, an immutable array of Bar contains an immutable array of int, whereas mutable would contain mutable, so you can't convert without a deep dup.

I assume it was fixed by pull 219 for issue 1339.

Here iarr.dup is returning an immutable array, which is then attempted to cast to the type of arr which is mutable. Hence the error.
