Besides the compile-time issue, I don't see why this is "clearly not right"?!
Also, I'm quite sure that this not only applies to SPREAD, but very likely to
all other F2003 simplifiers implemented in 4.5.
As noted in the PR, I strongly believe that the linear constructor list needs
to go more sooner than later.
That said, ok as a workaround for trunk for now - but not for 4.4 (there is no
such simplifier for spread ;)
