#307 foreach clashes with "node contents" option

[Ignasi]

It's not possible to draw nodes through \foreach if nodes have node contents option.

Minimal not working example (with TikZ 3.0)

%---------------------------------------
\documentclass[tikz,border=2mm]{standalone}
\begin{document}
\begin{tikzpicture}

\foreach \i in {1,2,3}
\node[node contents=a] at (\i,0) ;

\end{tikzpicture}
\end{document}
%---------------------------------------

It finishes with:

---

! Use of \@next doesn't match its definition.
\pgffor@body ->\node [node contents=a] at
(\i ,0) ;
l.6 \node[node contents=a] at (\i,0) ;

?

Complete .log file is attached

Quoting the manual;

When the option is used inside the options of a node, the parsing of the node stops
immediately after the end of the option block

When using node contents, node location requires at=<(coord or name)> syntax as an option. The following works;

    \begin{tikzpicture}
    \foreach \i in {1,2,3}{
    \node[node contents={a},at={(\i,0)}] ;
    }
    \end{tikzpicture}

However, as far as I can see, there is no need to use node contents in this context if you would like to keep the at <(coord or name)> syntax on the path.

In fact I needed to specify node contents in .style declaration. I didn't know that at was also possible in node options.

Issue solved from my point of view.
