Wi 9.8.0-beta

---

Added

• wi_abi_version and wi_check_version/WI_CHECK_VERSION (API)
• std::call
• io::stdin, io::stdout, and io::stderr

Changed

• The main script path is now included as the first item in os::args

• C stack overflow not being detected through foreign calls
• Off-by-one in the global and constant limits
• Missing write barriers in variable definition
• Function fields recursing into themselves
• Implicit returns not getting TCO
• Switch not requiring its closing brace
• wi_pcall leaving the callee's upvalues open on failure

• std::equals missing the C stack overflow check
• io::writebytes error messages
• array->slice with an empty slice
• Off-by-one in stack accounting in returns
• Interrupts being ignored after foreign calls
• string->select/where leaking on error
• string->each not returning the string
• Lexer errors pointing at the wrong character
• std::try hanging forever on stack overflow
