Thanks! I was looking for such a general-purpose proposal but could not find it. 

Although general-purpose mechanism that would allow pluggable constructs like `sh`, `html`, `sql` and the like is awesome and very desirable (especially sh in preference of Popen madness), string formatting/concatenation is IMO a fundamental concept (hence PEP-498 is in core with specialized opcodes instead of being deferred to be a general purpose pluggable PEP-501 implementation).
