These two occurrences of "PrimaryExpr" are problematic. Consider the section's second example: $f[2]("Hi there") The function item that is invoked is returned by $f[2], which is not a PrimaryExpr. The PrimaryExpr is $f, which does not return a sequence consisting of a single function item. I suggest we change "PrimaryExpr" to "base expression", in parallel with 3.2.1 "Filter Expressions". 61432 1 jonathan.robie 2011-12-11 19:40:40 +0000 I believe this is fixed in the current internal Working Draft.
