Maybe it's on the same level as the Lambda Abstraction (14.5), but you'll probably have to do some testing to figure it out exactly. precedence levels seem to be defined in `src/parse.h` (the `PREC` enum) and assigned to operators in `src/parse.c` (`initPrecedence()`).
is there any reason UFCS can't be used with 'new'?
i want to chain 'new' with method calls on the created object. i found this on the internet: window.mainWidget = (new Button()).text(Hello worldd).textColor(0xFF); it would look much nicer with UFCS: window.mainWidget = Button.new().text(Hello worldd).textColor(0xFF); well, it's not *exactly* UFCS but you get what i mean.
Re: is there any reason UFCS can't be used with 'new'?
thanks! but i'm still interested *why* you can't have this with
'new'. if there's no good reason i will file a bug report.

fwiw here's what i wrote:
template New(T) if (is(T == class)) {
T New(Args...) (Args args) {
return new T(args);
}
}
...
New!Bar(hi).txt.writeln;
not as neat as your version but still improves on the ugly (new
Class()).method syntax and doesn't need to be mixed into the
class definition.

thanks! where should i put it in this table:

Is there a function that reads the entire contents of a std.stdio.File?
all the functions/methods i've come across so far deal with either streams or just file names (like std.file.read) and there doesn't seem to be a way to wrap a std.stdio.File in a stream (or is there?). i need a function that takes a std.stdio.File and returns a string or byte array.

I usually use something like this: // Lazy auto stream = stdin.byChunk(4096).joiner(); You can make it eager by tacking a `.array` on the end. Functions used are from std.stdio, std.algorithm, std.array. thanks. that's exactly what i need.
