I think that the issue here is not about syntax as much as it is about
semantics:
As others said, this is equivalent to dynamic language's eval() or to D's
string mixin and the this raises the question of hygiene which sadly has no
good solution in D.
The main concern is this:
In what context are the symbols 'a' and 'b' evaluated?
At the moment they cannot be correctly evaluated at the caller context and do
not allow:
sort!("a.foo() > b.bar()")(whatever);
The bikesheding of the syntax does not address this concern at all.
