Err... no.  This actually causes previously successful parsing to fail.
The two are not equivalent.

The problem was elsewhere:

    start %= identifier >>
        ((attr(false) >> ifs2d)
        | (attr(true) >> ifs3d));

needed to become:

    start %= (identifier >> attr(false) >> ifs2d)
        | (identifier >> attr(true) >> ifs3d);

It seems the attribute signature of the first is:

tuple<string, tuple<bool, ifs_transform>>

and the signature of the second is

tuple<string, bool, ifs_transform>

This latter signature is compatible with the fusion signature of my
structure, but apparently the former is not.
