Have no idea at which stage in the "decoding" sequence name aliases are resoved, which certainly determines the difficulty of implementing the feature. Anyway, since D's term is 'alias', this term should be used in error messages instead of 'aka'. Also, 'aka' can be difficult for non-english speakers (have learnt it myself only recently, after decades of English practice). 'alias' does not have this issue due to beeing part of D's terminology. However, it goes in opposite sense, I guess: test.d(4): Error: no property 'x' for type 'Foo' (alias for 'int') Or maybe suppleness of English allows the following to be clear? test.d(4): Error: no property 'x' for type 'Foo' ('int' alias) Denis -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=5004 Another similar example of bad error message, DMD 2.054: enum Foo { A } void main() { auto x = Foo.B; } test.d(3): Error: no property 'B' for type 'int' -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=5004 One case: alias ushort UT; void main() { int x; UT y = x; } DMD 2.060alpha gives: test.d(4): Error: cannot implicitly convert expression (x) of type int to ushort But a more useful error message is similar to: test.d(4): Error: cannot implicitly convert expression (x) of type int to UT (alias for ushort) See also Issue 8044 -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
