digitalmars.D.learn - Demangling D Symbols when Profiling D Programs with perf

I've just discovered the fantastic tool perf on Linux.

I profiled a D program with this but when I call

     perf report

the symbols are not demangled.

I'm aware of `ddemangle` but this only works in batch-processing 
mode. I could always dump the output to a file for viewing. But 
it would be great if someone have found a solution to demangle 
the symbols *before* they are added to the perf database file.
