[Issue 2056] Const system does not allow certain safe casts/conversions involving deep composite types
http://d.puremagic.com/issues/show_bug.cgi?id=2056 --- Comment #4 from Bruno Medeiros bdom.pub+deeb...@gmail.com 2010-11-18 04:06:29 PST --- A regression? Not exactly. When this bug was submitted, the lines marked with // Error here did not compile, and that was the bug that was reported. At some point DMD was changed so that the first, and later both code samples above compiled without errors. (I don't know if it was because Walter tried to fix this bug specifically, or if it was due to some other DMD changes). So this bug became fixed, but as I found after seeing #2544, this bug is actually invalid, and should not have been fixed in the first place. ( For curiosity, it would only be valid if immutable did not exist, or more precisely, if T was the only subtype of const(T) ) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

For the reasons why, see bug #2544 , which is the inverse of this one. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
