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.
