 Options 1 and 2 have their pros and cons, but 3 and 4 are easily confused due to overlapping syntax, are strictly less capable than the first two options, and are rarely used in practice.  Option 3 is specifically less capable than 2, and option 4 has different semantics (dynamic variable lookup) that is rarely useful in string interpolation. Options 1 and 2 have their pros and cons, but 3 and 4 are easily confused due to overlapping syntax, are strictly less capable than the first two options, and are rarely used in practice.  Option 3 is specifically less capable than 2, and option 4 has different semantics (dynamic variable lookup) that is rarely useful in string interpolation.
