Subject: RE: [xri] Sticky star examples
Marty, Yes, that is my understanding of the definition of sticky stars (and bangs.) You may be correct that B is not valid syntax.

Please let me know if I got it right: a star/asterisk, being a local delimiter, keeps the following term in a local context, and causes the xref in which it appears to continue. If that's correct, then I suppose we also have sticky bangs. I don't think example B is valid syntax, but as I'm still learning, I'd like to make sure I'm not mistaken. I think there needs to be an asterisk in front of the left paren in example B.

A: FOUR TOP-LEVEL SUBSEGMENTS ------------------------------------------------ XRI: =a+b*c+d global-literal = typeless-literal a global-xref +b*c global-literal + typeless-literal b local-literal *c global-xref +d global-literal + typeless-literal d B: FIVE TOP-LEVEL SUBSEGMENTS ------------------------------------------------ XRI: =a(+b)*c+d global-literal = typeless-literal a typeless-xref (+b) global-xref +b global-literal + typeless-literal b local-literal *c global-xref +d global-literal + typeless-literal d Thx, ~ Steve PS: I hate sticky stars! If someone wants that order of precendence, then THEY should use parens (as in =a(+b*c)+d) -- not the other way around. In other words, I think that both XRIs A and B above should have 5 top-level subsegments.
