Description:
Python has had formatted string literals ( f-strings ), a syntactic shorthand for building
strings, since 2015. Recently, Jim Baker, Guido van Rossum, and Paul Everitt have
proposed PEP 750 ("Tag Strings For Writing Domain-Specific Languages") which would
generalize and expand that mechanism to provide Python library writers with additional
flexibility. Reactions to the proposed change were somewhat positive, although there was a good deal of discussion of (and opposition to)
the PEP's inclusion of lazy evaluation of template parameters.
