Crash in expression = [...myvar]

[Melkor333]

The following crashes (on my mobile phone, couldn't test on desktop) with the tarball including the GLOB_PERIOD fix:

ysh-0.26.0$ var y = [1,2]
ysh-0.26.0$ = [...y]
_gen/bin/oils_for_unix.mycpp.cc:54671: syntax_asdl::expr_t *expr_to_ast::Transformer::Expr(pnode::PNode *): assertion "0" failed
Aborted

I'd like to be able to copy an arrays which sadly doesn't work simply that way :(

Oh yeah this is a bug, thanks for the report

For now you can use var x = list(y) ++ [4,5,6]

I would like for YSH to support this, but for now I added a proper syntax error

Will be out with the next release

===== CASE: -n -c = [42, ...y] =====


  = [42, ...y]
