So, I'm just interested in other people's thoughts are on the subject, and whether there are any plans to allow overloading these operators separately.
The limitations are deliberate based on the idea that comparison operators need to be consistent and predictable, and should have a close relationship to the mathematical meaning of the operators. Overloading <= to mean something other than "less than or equal" is considered poor style in D, and the same goes for the other arithmetic operators.
The use of them to create DSLs (a technique called "expression templates" in C++) is discouraged in D, for several reasons. The recommended way to create DSLs in D is to parse strings using CTFE. An excellent example of that is the std.regex package.
There are no plans to change this.
