Implementing std.log

[Andrej Mitrovic]

I'm not a big fan of that format syntax. It's just hard to look at and
figure out what went wrong when things do go wrong.

I'd prefer something like:

But someone would have to implement it, of course. I have my own
little echo() function which takes simple "{}" positional syntax, it
doesn't have any other formatting options though. But I only ever need
formatting for simple cases like the above. It seems some people need
a whole word processor macro language embedded in a format string..
