Template `std.functional.binaryFun`

Transforms a string representing an expression into a binary function. The string must either use symbol names a and b as the parameters or provide the symbols via the parm1Name and parm2Name arguments. If fun is not a string, binaryFun aliases itself away to fun.


						
				template binaryFun(alias fun, string parm1Name = "a", string parm2Name = "b")
				;
