Thoughts on new syntax for toclose

[Dibyendu Majumdar <mobile@...>]

The latest commits show the syntax <toclose> being adopted instead of *toclose.

Aesthetically I find the new syntax to be nicer, but this still has
the problem that the previous syntax had; which is that the symbol '<'
has meaning in expressions therefore using this symbol (like the *
symbol) may restrict the ability to use extensions inside expressions.
Of course extensions will always be restricted to local declarations
in which case it doesn't matter.
