[stringtemplate-interest] [RE:] Re: i0 with alternating templates

[Terence Parr]

Hi Guys,

Sure. I decided that i and i0 should not be dynamically scoped / visible to invoked templates.  sometimes very hard to figure out what i is and particularly when nested {...} are used.  So it never is dynamically visible.

t() ::= "<i>"

is a bit odd, right?   no parameter def.

t(n) ::= "<n>"

is better. then we can use i from {...}

<data:{<t(i)>}>
