Whatever happened to String Interpolation?

Ambiguity:

    Is that "the result of function f on variable x" or "the value of
    variable f, with the literal '(x)' after it"?

This slippery slope is one of many reasons many Pythonistas don't
want creeping featurism to infect their language.

(Perl has ways of disambiguating(?) the above expression, but it
leads to ugly code Pythonistas love to make fun of. eg:

    "x is $x, f(x) is @{[&f(x)]}"

That's the perl equivalent. )

distance in order to be able to consider the bug dispassionately.
