If it doesn't compile, there must be an error message. They're generally
useful for debugging.

Don't know what the issue is, but there are two issues here, a syntax one,
and a bug:
1. there should be a "." between "that" and "@fr.gouv.finances.…":
[email protected].…
2. the $entry() is not correctly used: $entry() wraps a function so that
calling the returned function executes the scheduledEntry and
scheduledFinally commands, and route exceptions through the
GWT.UncaughtExceptionHandler; but here you're wrapping the return value of
your method, after calling it, and you don't use the return value of
$entry(); so it's useless.
Best is to wrap your anonymous function with $entry: $wnd.modifyTabTitle
= $entry(function(title) { ... });
