Also, if you do not need to write to a stream or a range and just 
need the value, `format("%s", value)` works as well as std.conv's 

But between the two functions, it seems that the only difference 
is that `formattedWrite` only accepts the exact values that go on 
the output range (such as an integer), and `formatValue` has 
extra logic to convert structs, classes, and unions into strings 
by calling their `toString()` method.
