-* Very long instructions are supported, up to SPIR-V universal limits.
-* 32 and 64-bit floating point literals are encoded properly.
-* Signed and unsigned integers up to 64 bits wide are supported and encoded
-  properly.
-* Hexadecimal literals are supported.  See `syntax.md`.

+     The assembler checks that other literal numbers are non-negative integers.
+     That's the grammar works, at least for now.
