\ rakudo-moar 8b40d1: ( no output )
\ yeah, I missed the .new in my example, but the result is the same, no?
\ binding just doesn't work
\ right
\ are assignments to native attributes already just nqp::bindattr?
\ er, not "native"
\ but that kind of makes it awkward to put Scalar objects into attributes and assigning binds the new value to replace the scalar instead of assigning into the scalar?
\ except if you use accessors, you potentially get an AttrRef that's scalar-like? perhaps?
\ what I want to achieve is to bind an nqp::list from a '$!reified' slot
\ if I just assign, I get this:
\ $ 6l 'my @a[10] = ^10; say @a.iterator.pull-one'
\ Segmentation fault: 11
\ :-(
\ ok, I guess I'll work around it :-(
\ timotimo: do you agree this is buggable ?
\ huh, ouch
\ lizmat: all segfaults are buggable
\ quite
