I find the the symbol way more consist with the different usage possibilities.
{:keys [a] :or {a :x}}
{:syms [a] :or {a :x}}
{:strs [a] :or {a :x}}
{a 1 :or {a :x}}
No special cases. Just one thing to remember. And easier to parse. Compare to:
{a 1 :or {1 :x}}
It is not clear what 1 refers to. You have to check also the rest of the
destructuring to understand it, while ":or {a :x}" is pretty much
self-explaining.
Sincerely
Meikel
