Bug 18252 – [Reg 2.078] comparison of arrays of associative arrays no longer compiles

Tow arrays of associative array can't be compared. Compiler: DMD 2.078 Error message: D:\Dlang\dmd2\windows\bin\..\..\src\druntime\import\object.d(3461,31): Error: no property 'tupleof' for type 'string[int]' D:\Dlang\dmd2\windows\bin\..\..\src\druntime\import\object.d(3461,53): Error: no property 'tupleof' for type 'string[int]' source\app.d(11,6): Error: template instance object.__equals!(string[int], string[int]) error instantiating dmd failed with exit code 1. =====Test code====== import std.stdio; import std.algorithm; void main() { bool r; string[int][] aa1; string[int][] aa2; // r = __equals!(string[int], string[int])(aa1, aa2); // bug r = aa1 == aa2; // bug // r = equal(aa1, aa2); // ok }

This is a regression introduced in 2.078

Probably due to https://github.com/dlang/druntime/pull/1824

cat > bug.d << CODE void foo() { string[int][] aa1, aa2; auto r = aa1 == aa2; } CODE Digger says: https://github.com/dlang/dmd/pull/7225
