I suppose that you are bothered by:
X = 3000
Because that is the same as mov x,3000 in virtually all of the early assemblers.

It served a purpose. Don't blame it on intel, blame it on DEC and
IBM. Ever program a PDP8, or an IBM360?
When intel settled on the CS,DS,ES, SS architecture, they did so because
it made it easy to write pascal compilers. Someone in the computer science
world told them that pascal was the way to the future. I guess they were
