* from_json: number-first dispatch for arithmetic types, loop for std::array (#5891) from_json(ArithmeticType&) now reads numbers through get_number_value() and handles a boolean on a cold path, which puts the three number types first in the per-element type dispatch. get<std::array<T, N>>() always took the identity_tag overload, a pack expansion of N calls j.at(i).get<T>() that clang unrolls into straight-line code (about 28,000 instructions for N = 1000), so its speed depended on inlining decisions in that body. For trivial element types, which cannot tell default construction plus assignment from construction in place, it now fills a std::array in a loop. That loop, shared with get_to(), checks the size once and reads the inner array directly; a short array still converts the elements it has and then throws the out_of_range error at() would throw.
