Summary: Misleading error message when passing non-existent
symbol to template
Product: D
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: bugzilla at digitalmars.com
ReportedBy: andrei at metalanguage.com
Prompted by a post by Bryan Myers:
import std.string;
import std.algorithm;
void main(char[][] args)
{
string[] words = ["c", "ab", "bb"];
sort!("a < b", SortStrategy.stable)(words);
assert(words == ["ab", "bb", "c"]);
}
The code uses the non-existent symbol SortStrategy.stable instead of the
correct SwapStrategy.stable. However, the error message implies that the symbol
does exist and has type int:
/home/andrei/test.d(8): template std.algorithm.sort(alias less,SwapStrategy ss
= SwapStrategy.unstable,alias iterSwap = .iterSwap,Range) does not match any
function template declaration
/home/andrei/test.d(8): template std.algorithm.sort(alias less,SwapStrategy ss
= SwapStrategy.unstable,alias iterSwap = .iterSwap,Range) cannot deduce
template function from argument types !("a < b",int)(invariant(char)[][])
