When is it pointless to introduce a WriteStream and just use #, ?
When #, would not be in a loop or recursion.
Constructing error messages, class initialisation code, that sort of thing.

If you find yourself doing a lot of concatenations, you are probably
missing an abstraction. For example, building up XML by string
concatenation would be very silly: you want to build a tree and have
it write itself to a stream.
Absolutely agree. Streams use logarithmic extension of buffer, concatenation linear, but it is still amazing to see.
I am working on a pillar to `Text` generator. Here I found concatenation to be simpler to handle as I can add bold, italics, indentation, etc. in a much simpler way. To use a streaming method I would have to introduce both Canvas and Aggregate brushes. Doable indeed, but much less concise.

I started to do exactly the same. Well I started to do a converter between pillar markup and text attributes, but I think you do the same. We probably should talk. Is you code anywhere public?
