First, I must say that I like your approach. Code speaks much louder than
There are two reasons I can think of why anyone would feel that Python
needs new syntax for string interpolation:
1. One likes his syntactic sugar extra-sweet and feels than even an import
statement and an extra pair of parens is too bitter.
2. One likes all the expressions in his code syntax-checked at compile time
and converted into bytecode without the use of runtime evaluation.
PEP 215 appears to be written with #1 in mind. My PEP draft for string
interpolation is mostly concerned with #2.
If the BDFL ever decides to implement string interpolation he should have
more than just one proposal to choose from.
