[myhdl-list] omiting .next should cause an error

[George P. <ge...@ga...>]

Hi Jan,

    I've often run into the situation where I forget to use .next for a 
variable, and it produces subtle errors that are hard to detect.

(eg. doing "count = (count + 1) % 2**COUNTER_WIDTH", rather than doing 
"count.next = (count + 1) % 2**COUNTER_WIDTH)". I often slip up because 
I'm very used to programming in C/C++ at work. I feel that myHDL should 
flag this as an obvious error.

Thanks,
George
