http://d.puremagic.com/issues/show_bug.cgi?id=5147 Summary: [CTFE] Return fixed-sized matrix Product: D Version: D2 Platform: x86 OS/Version: Windows Status: NEW Keywords: rejects-valid Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody@puremagic.com ReportedBy: bearophile_hugs@eml.cc --- Comment #0 from bearophile_hugs@eml.cc 2010-10-31 14:20:21 PDT --- This is borderline between enhancement and rejects-valid bug report. DMD 2.050 doesn't support this code: int[1][1] foo() { int[1][1] a; return a; } enum int[1][1] m1 = foo(); immutable int[1][1] m2 = foo(); void main() {} Errors generated: test.d(2): Error: Slice operation a[] = 0 cannot be evaluated at compile time test.d(5): Error: cannot evaluate foo() at compile time This code is very useful to initialize an enum/immutable global matrix. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

It applies to any use of multidimensional static arrays in CTFE (not just return values). Thus, it also applies to D1. Fixed.
