- * A note to trio contributors:
- *
- * Avoid heap allocation at all costs to ensure that the trio functions
- * are async-safe. The exceptions are the printf/fprintf functions, which
- * uses fputc, and the asprintf functions and the <alloc> modifier, which
- * by design are required to allocate form the heap.
- *
- ************************************************************************/

-/*
- * TODO:
- * - Scan is probably too permissive about its modifiers.
- * - C escapes in %#[] ?
- * - Multibyte characters (done for format parsing, except scan groups)
- * - Complex numbers? (C99 _Complex)
- * - Boolean values? (C99 _Bool)
- * - C99 NaN(n-char-sequence) missing
- * - Should we support the GNU %a alloc modifier? GNU has an ugly hack
- * for %a, because C99 used %a for other purposes. If specified as
- * %as or %a[ it is interpreted as the alloc modifier, otherwise as
- * the C99 hex-float. This means that you cannot scan %as as a hex-float
- * immediately followed by an 's'.
- * - Scanning of collating symbols.
