I'm sorry. Actually, my explanation above is wrong, because the
right-hand side of the assignment for the declare builtin is not a
context where word splitting.happens. The word splitting happens
because the declare builtin receives the literal '(one 1 two 2 two and
a half 2.5 three 3)' and parses it again. Anyway, the current behavior
for the latter example is expected in my understanding.
