trying to compile the latet phobos revision, I've hit this assert:

std\bind.d(295): Error: static assert  (isTypeTuple!(Tuple!(int))) is false

which boils down to the template isExpressionTuple not returning the correct value. This is caused by

alias int myint;
enum var = myint;

being accepted as correct syntax while "enum var = int;" is not.

This happens for every DMD version I have tested (latest svn, 2.046, 2.042,
1.056).

Strange that you're getting this in 1.056 - I've always understood enums without {} to be a D2-specific feature.  I certainly can't reproduce under 1.061.

But under 2.046:

----------
alias int myint;
enum var = myint;

pragma(msg, var);
pragma(msg, typeof(var));
----------
int
bz4206.d(5): Error: argument int to typeof is not an expression
void
----------

This should error at line 2 - myint is a type, not a value.

But I wonder if it's by any chance related to issue 2414.

You're right, it correctly does not compile with dmd 1.056. I must have been halucinating. Also, "enum { var = myint };" causes an error.

The use case that was failing with D2 is

pragma(msg, __traits(compiles, { enum var = myint; }));

and outputs "true".

On dmd 2.054 (d36b3b12fc4814e59f3a0d680b8700e787b1ceff), issue 2414 may have been resolved. But "enum { var = myint };" does not cause an error.

I think this issue does not depend on 2414,
