Re: [LaTeX][PGF/TikZ] Undefined control sequence error for PGF intersections.

Don't know whether this is expected behavior or a bug.

  The TikZ & PGF manual (for Version 3.1.5b) has got this entry
  "/tikz/intersection/total=<macro>" in the "13.3.2 Intersections
  of Arbitrary Paths" section. It's got this example where
  the "\foreach \s in {1,...,\t}" is all indented and stuff.

|\usetikzlibrary {intersections}
|\begin{tikzpicture}
|  \clip (-2,-2) rectangle (2,2);
|  \draw [name path=curve 1] (-2,-1) .. controls (8,-1) and (-8,1) .. (2,1);
|  \draw [name path=curve 2] (-1,-2) .. controls (-1,8) and (1,-8) .. (1,2);
|
|  \fill [name intersections={of=curve 1 and curve 2, name=i, total=\t}]
|        [red, opacity=0.5, every node/.style={above left, black, opacity=1}]
|        \foreach \s in {1,...,\t}{(i-\s) circle (2pt) node {\footnotesize\s}};
|\end{tikzpicture}

from "TikZ & PGF" "Manual for Version 3.1.5b".

  If you drop a semicolon in front of the "\foreach" (right after
  "opacity=1}]"), it's going to wig out on you with that error message.

  Well, "\fill" is shorthand for "\path[fill]", and the 411 on
  "\path" syntax is dropped in "14 Syntax for Path Specifications",
  which lays it down like this:

|\path<specification>;

  . So, there's that semicolon hanging ten, but I'm not stoked on where
  its implications for the scope of "name intersections" is posted up.
