Detailed Description

template<typename T>
struct microfmt::detail::fix_type< T >

Collapses argument types to a canonical representative before they reach format_type_table, so that types differing only in ways that format_type_thunk doesn't actually care about don't each generate their own thunk/table instantiation.

String-literal arguments are the main offender: "hi" and "hello, world!" deduce to distinct types (char[3], char[14], ...), yet format_type_thunk always treats a bounded char array as "pointer to its first element" and never inspects the bound N, so every length is functionally identical. Collapsing them to a single-element array keeps the array-vs-pointer distinction (and constness) that format_type_thunk relies on while eliminating the combinatorial blowup of thunk/table specializations (and therefore binary size and compile time) across call sites using differently-sized string literals.
