    In this week's SV-BC meeting, we reviewed SV-BC42-1.

    SV 3.0 section 3.3:
    Are bit selects of int, byte, char,etc. allowed? Clarification is needed
    on what data types bit selects are allowed on, and which bit number ot use
    for the LSB. SystemSim 2.1.4 does not allow bit selects of an int, for
    example, but Peter Flake tells me it should be allowed.

    Steven Sharp's response to this is that IEEE 2001 does not allow bit
    selects of integer types, although most simulators support it. We would
    like to clarify this part of 2001 before we implement similar functionality
    in SystemVerilog.
