The issue is still present (3/16/14). Concatenation of an empty string value, '' or "", with a struct results in an error.

This is an old report, from 2011, but the issue is still there (6/21/13). Since the parser has undergone significant work, can we make a call about whether we should support promoting empty strings to nulls for concatenations with structs?

The following should all work

but the character string versions fail on invalid conversions.

Should we be treating literal null matrices specially in tree_matrix::rvalue1 in pt-mat.cc? Because of the way that function handles initial empty values, it seems that functions like
oct_catop_matrix_struct in op-struct.cc are not called in all cases. Or maybe they are never called? In what cases are they be called? Should they be called for all empty value cases? Just for non-literal empty matrices? At this point, I'm obviously not sure what the right fix is...
