I don't like most of Ruby, but, after using Crystal and CoffeeScript, I have fallen in love with #{}. It gives the appearance of a real expression, not just a format placeholder. Like:
f'a#{name}b'
That's what I'm talking about. It's not a placeholder. It's not a duplicated name that references a keyword argument at the end of the expression. It's an actual expression.
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).
