I'm looking for elegant ways of expressing expansion of parameterized strings written to a file at run-time. My primary use case is run-time generation of D code. In the lazy case, something like

    import std.file : write;
    import std.algorithm : substitute;
    const s = q{int $X = $Y;}; // templated source
    foreach (part; s.substitute("$X", "x", "$Y", "42"))
        write(somePath, part);

is my current best bet.

You might want to have a look at Mustache [1]. Here's a Dub package [2].
