http://d.puremagic.com/issues/show_bug.cgi?id=3766 Summary: Pointers to pure, nothrow functions be subtypes of regular functions Product: D Version: 2.040 Platform: Other OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: dsimcha yahoo.com void nothrowStuff() nothrow {} void pureStuff() pure {} void stuff() {} auto funcPtr = (0 == 0) ? &stuff : ¬hrowStuff; auto funcPtr2 = (0 == 0) ? &stuff : &pureStuff; test.d(5): Error: incompatible types for ((& stuff) ? (& nothrowStuff)): 'void function()' and 'void function() nothrow' test.d(6): Error: incompatible types for ((& stuff) ? (& pureStuff)): 'void function()' and 'void function() pure' void function() pure and void function() nothrow should be considered subtypes of void function(). A void function() pure or a void function() nothrow simply provides an extra guarantee not present for void function() and thus can be substituted in any context for a void function(). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
