Was just looking at the examples on std.format. There is also 
this:
writeln(format("%,f", 1234567.891011)); // "1,234,567.891,011"
which is what you would expect, I suppose, but still isn't what 
anyone would want. What you'd want is
writeln(format("%,.0f", 1234567.891011)); // "1,234,567"
which may not currently be tested.

Someone should file a bug report.
