Well, in D functions can only return one value. So you cannot compose
them with functions asking for more than one argument.

For example, your code allows Algorisme!(int, double, string,
float[]), which needs a 3-tuple as input (namely,
(double,string,float[]) ) and returns an int.
What kind of other Algorisme could be used as input for the one before?
In general, you'll compose only functions taking one type and
returning one type.

Except if you auto-detect a std.typecons.Tuple and crack it open, I guess.

Right Hand Side (as opposed to lhs, Left Hand Side), the thing on the
right-hand side of the operator. Sorry for the acronym.
