xst 9.0.1

This release is focused on enhancing the XS linker.
See XS linker warnings for details.

This release features two proposals:

• Top level await
• Weakrefs

There are also a lot of fixes, mostly to get correct “ticks” for async functions and generators.

The xst options changed to be more compatible with other engines:

xst [-h] [-e] [-m] [-s] [-t] [-v] strings...
	-h: print this help message
	-e: eval strings
	-m: strings are paths to modules
	-s: strings are paths to scripts
	-t: strings are paths to test262 cases or directories
	-v: print XS version

Without -e, -m, -s, or -t, strings ending in .mjs are paths to modules, other strings are paths to scripts.
