I was surprised to find this when building the list too, but I believe
it's unrestricted.

The GLSL 4.0 spec, 4.3.7 p43 (bottom of) says:

    "Any integral expression can be used to index a uniform block array."

The corresponding language for arrays of samplers is:

    "...a dynamically uniform integral expression, otherwise results
are undefined."
