Array of struct not allowed as parameters

Problem

Posting this as a result of this comment made by Larry.

Not sure this is really a problem, but Larry thought it might be.

Currently this generates a compile error.

struct textureresource
{
    string filename;
    string colorspace;
};

shader test_shader
(
    textureresource files[2] = {{"",""},{"",""}},
    output float out = 0
)
{}

generates the following compile error.

> oslc test.osl
test.osl:9: error: array of struct are not allowed as parameters
FAILED test.osl

Steps to Reproduce

1. compile code above.
