Good catch! :) Welcome to D where static arrays (aka
"fixed-length arrays") and dynamic arrays (aka "slice

That should be:
reduce() is an algorithm that _does not require_ more than an InputRange.
(That is also misleading: reduce() requires an "iterable object", which
can be any type of a range,

Good catch! :) Welcome to D where static arrays (aka "fixed-length
arrays") and dynamic arrays (aka "slices") are different beasts.
A number of factors are at play her

That error tells you to not use an int as first value for the
reduce. Maybe this is enough to solve your problem.

I have an array of objects that have a size() property. Code to
sum them manually works fine, as expected:
auto total = 0;
foreach (wt; _word_tables)
total += wt.size();
return total;
How can I do this with reduce? (BTW I second the old comments and
bugs about not having sum() built
