--- Comment #2 from Rob Jacques <sandf...@jhu.edu> 2011-02-03 09:46:11 PST --- I apologize for the bad test case. In retrospect, I believe I didn't try to reduce it, I simply extrapolated the issue from the error message reported. Here is a properly test case: import std.string; pragma(msg, replace(int.stringof,"int","real")); Which generates the error: C:\dmd2\src\phobos\std\functional.d(177): Error: static assert "Bad binary function q{a == b}. You need to use a valid D expression using symbols a of type dchar and b of type const(char)[]." C:\dmd2\src\phobos\std\functional.d(180): instantiated from here: Body!(dchar,const(char)[]) C:\dmd2\src\phobos\std\algorithm.d(2149): instantiated from here: result!(dchar,const(char)[]) What got me was that algorithm.d(2149) turns out to be: 2147: R find(alias pred = "a == b", R, E)(R haystack, E needle) 2148: if (isInputRange!R && 2149: is(typeof(binaryFun!pred(haystack.front, needle)) : bool)) However, this only seems to generate a bug in certain compile-time contexts. For example, enum bug = replace(int.stringof,"int","real"); compiles, while: import std.typetuple; mixin( "alias TypeTuple!("~replace(int.stringof,"int","real")~") This2Algebraic;"); doesn't. Although I don't know how/why find is called. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
