Template std.functional.unaryFun
Transforms a string representing an expression into a unary
function. The string must either use symbol name a
as
the parameter or provide the symbol via the parmName
argument.
If fun
is not a string, unaryFun
aliases itself away to fun
.
template unaryFun(alias fun, string parmName = "a")
;

assert(isEven(2) && !isEven(1));
