Do mixin templates work on module level? They can even have an identifier.

Yes. But a mixin template seems only be able to contain declarations. How did you plan to use it?

As Atila posted.

Unfortunately there are syntactical ambiguities:

     step("foo bar") {

Is that a call chain, or two statements, with the second one calling a function in the root scope? And I think there are other similar cases...

Hmm, right. I have simple implementation of this. With you're example I get this error message:

function main.foo () is not callable using argument types (void function() @safe)

I guess we could even live with that. If someone wants the latter interpretation (which is kind of infrequent), they could insert a semicolon.

Does your implementation support parameterized lambdas? I can already see the next ambiguity:

    someRange.each (element) {

Do the parentheses belong to the lambda on the right or the function on the left?
