And I have missed this is my cleaning of the code :-)
Bye,

Few notes:
- opCall() of AvgWeighted was abstract.
- keep in mind that in D classes are CamelCase;
- variable names are written like weightSum (but once in a while a underscore
doesn't kill).
- Be careful because ref arguments are tricky.
- There is a line like foreach (r; reputationUser) r = 1; t

The errors are for the missing definitions of that function. Either
provide a definition, or just remove that declaration
Hello everyone,
A probably stupid but I-can't-find-the-solution-with-Google problem.
I'm trying to compile a small project I'm working on to learn D, called
'dregs'. It's just 3 files for now (2 modules plus a little test program).
Unfortunately every time I try and compile, I get 'undefined ref

You have to take a look at what the compiler does normally. It doesn't do magic.
Generally a function is something that takes a run-time value with a simple
protocol. So when an argument is inside a function, it's a variable, even if
the function was called with a constant.
