I'm referring to the syntax, though. It makes it visually distinct from normal format string placeholders.

Also: plain format strings are a *pain* to escape in code generators, e.g.:

print('int main() {{ return 0+{name}; }}'.format(name))

Stupid double brackets. That is why I still use % formatting.

#{} isn't a common expression to ever use. I have never actually printed a string that contains #{} (except when using interpolation in CoffeeScript/Crystal).
