Not sure about introducing yet another string prefix. Between f-strings, raw strings, and i18n stuff, it’s already getting crowded. Curious how readable this will be in large codebases.

from sql import sql
query = sql"SELECT user_id, user_name FROM {user_table_versioned} WHERE user_name = {user_name}"The syntactic sugar of changing it from sql(t"...") doesn't seem particularly valuable. The novel thing about t-strings is that they change the parsing at compile-time.
There’s nothing stopping you from building a Python function that parses a string looking for {} and then searching globals for those variables. And you can extend that to also do some code execution and formatting.
To me the real sugar of f-strings is that the editor knows that it’s a template and not just a string. Expanding this to having SQL and regex syntax highlighting, linting and code formatting inside my Python code is a pretty cool prospect.
