Function Templates
Explore how to create function templates in D that enable type-independent coding by leaving types unspecified for compiler deduction. Learn to define multiple template parameters for enhancing function flexibility, allowing code to handle varying data types and custom parentheses characters effectively.

Defining a function as a template means leaving one or more of the types it uses as unspecified, to be deduced later by the compiler.
The types that are left unspecified are defined within the template parameter list, which comes between the name of the function and the function parameter list. For that reason, function templates have two parameter lists:
- template parameter list
- function parameter list
void printInParens(T)(T value) {
writefln("(%s)", value);
}
The T within the template parameter list above means that T can be ...
