map { some_condition ? $_ : some_default } some_expression;

Very good argument!

The syntax and operand order is confusingly dissimilar to the exiting ternary operator.

Pointless argument: why should it be similar to it? And how is that confusing? It's nonconfusingly similar to C<||> and C<//>. OTOH, while I cherish your map solution, which probably is actually the best one in 5's realms, if you look at it as a whole, it is confusingly dissimilar from those operators, with the value being inspected on the extreme right and the default buried in the block, not to talk of an "unnecessary" C<? $_ :. The right comparison if I get it right should be between:

map { some_condition ?? $_ !! some_default }, some_expression;
# and
some_expression ||| { some_condition }, some_default;
