The sadness of Open Source is that unlike businesses they don't see productivitylosses. They can just ignore them and pretend they don't exist. Thus they fail to benefit fom the synergies that are available to them.

We have few people, and if we don't organize ourselves, we cannot compete with other languages. They all have organized. Wake up,Walter(repeate 3 times).

Of course, forum =/= dmd

You better do something to recruit the ones that are still there unless you want to struggle with DIP1000 all by yourselves forever.

Eventually what could be done for the biggest methods of visitors is to extract parts of the content to several non-nested free functions, so that no more low level implementation details, like control loops, are visible and instead you just see do_this; do_that; with just a few, nzzcessarily unavoidable, flow statements.

I've had the opportunity to do quch a refact yesterday in styx. It makes things very clear, for example the expression semantic for binary assign exps :

override void visit(BinAssExpressionAstNode node)
{
    processBinaryOperands(node);
    if (tryRewritingToOperatorOverload(node, [node.left, node.right]))
        return;
    if (tryToSetLengthExp(node))
        return;
    if (checkIfInvalidEnumSetOp(node))
        return;
    if (checkPtrArithmeticOp(node))
        return;
    ensureAssignedParamIsLvalue(node);
    tryOneWayAssImplicitConv(node);
    checkIfAssignable(node.left);
}

or for binary exps that are not assign and not cmp:

override void visit(BinaryExpressionAstNode node)
{
    processBinaryOperands(node);
    if (tryRewritingToOperatorOverload(node, [node.left, node.right]))
        return;
    if (checkIfInvalidEnumSetOp(node))
        return;
    if (checkPtrArithmeticOp(node))
        return;
    tryTwoWaysBinaryImplicitConv(node);
}

It was like 200 lines before.
