http://d.puremagic.com/issues/show_bug.cgi?id=11130 Summary: Regression (2.064 git-head): Enum members hijack module-scoped symbols in initializers Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: regression Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: andrej.mitrovich gmail.com 06:34:40 PDT --- This may or may not have been an intended change: ----- enum A = 1; enum E { A = A } void main() { } ----- $ dmd test.d test.d(7): Error: enum member test.E.A circular reference to enum member The workaround is simple for module-scoped enums, use the [dot] expression to look up module-scoped symbols: ----- enum A = 1; enum E { A = .A // works } void main() { } ----- However the following code does not have an easy workaround: ----- void main() { enum A = 1; enum E { // circular reference, cannot use ".A" here // because "A" is not in module scope A = A } } ----- Above you would likely have to introduce an alias such as: ----- void main() { enum A = 1; alias thisA = A; enum E { A = thisA // ok } } ----- If this regression was intended we're going to have to properly document it, both in the docs and in the upcoming changelog. The regression was found in DGui, where some enum members have the same name as WinAPI constants, but were purposefully wrapped in the enum to make the constants typed: enum EdgeType : uint { RAISED_OUTER = BDR_RAISEDOUTER, RAISED_INNER = BDR_RAISEDINNER, SUNKEN_OUTER = BDR_SUNKENOUTER, SUNKEN_INNER = BDR_SUNKENINNER, BUMP = EDGE_BUMP, ETCHED = EDGE_ETCHED, EDGE_RAISED = EDGE_RAISED, // issue here SUNKEN = EDGE_SUNKEN, } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Before, an enum member was not inserted into the symbol table until *after* its initialization expression was evaluated. But in order for forward references to work, this is no longer possible, now all the enum member symbols are visible inside the { }. I am surprised this broke any code, I don't consider it a reasonable practice, but you're right that we need to document this behavior. I'm going to reset this as a "spec" issue. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
