Bug 14320 – Improve diagnostic message for "undefined identifier" error

-- gui/widgget.d ----- module gui.widget; class Style {} // originally existed in gui.style class Widget { Style style() {} void layoutChildren(bool fit, Widget positionReference) {} } ---- -- controls/tree.d --- module controls.tree; import gui.widget; class Tree : Widget { override void layoutChildren(bool fit, Widget positionReference) { gui.style.Style st = style; // line 9 } } ---- The error diagnostic is: controls/tree.d(9): Error: undefined identifier 'style' It actually explains the unexistent of module 'gui.style' in package 'gui', but it sounds like the explanation for the invisibility of Widget.style() function. I think it should be improved as follows: controls/tree.d(9): Error: undefined identifier 'gui.style' in package 'gui'
