Yep - typically involves building a big class library to support things 
like clocked processes and basic RTL structures & methods. The results 
end up looking a lot like most other HDLs and don't really run much 
faster. And of course this requires a translation shim to get it into 
any normal ASIC or FPGA synthesis/PAR toolflow.

As Stuart notes, you can operate at a higher level than some of the 
older spec'd HDLs, but a lot of higher functionality has been rolled 
into Verilog2k in the meantime so it's tough to say how much of an 
advantage it is.

And of course it has the disadvantage of allowing software types think 
that they can design hardware without any additional training. :) (ducks)
