Agree 100%. The last time we discussed this I proposed there should be a
function to do this. But the naive integrated syntax could be compile
My complaints with the current interpolation are:
1. they require too many magical incantations to invoke (especially %
2. they require too much thinking about types and conversions in the
3. special behaviour with dictionaries and tuples and singleton tuples
4. operator abuse
I would only be in favour of a replacement if for *simple cases* it
cleared up all of these issues so that it is roughly as easy as in
a = $"My name is $name"
If there is any more syntax than that then personally I think that the
cost/benefit ratio falls down. So I don't see this as a big win:
a = "My name is $name" \ locals()
It solves two of my four problems.
Maybe other people have different goals than I do and that's why they
see the above as a "win".
