To be honest, semicolons also help the readability of the code; they preserve the "List of instructions" feeling of the programming language; they work just like the semicolons in this sentence; they separate ideas while in the same context while if I didn't use semicolons (or much punctuation) then I'd end up with rather complicated ideas. In this case I am going to use no punctuation between words and leave the reader to decided when an idea ends like when for example I'm using a multi-line statement It's up to the compiler to decide when I finish a sentence conclusively given how difficult the past few sentences (while missing their "."s) are difficult to interpret it just improves the readability of the code and in this case my English and helps the reader understand the code/English at a higher level
.. Jeez that was painful to type. Sorry if my ideas weren't very easy to understand; there was a lack of information for you to properly parse make sense of it.
Oh and also, there are soooo many languages and developers that are used to the ; rule that it's like trying to advertise that just because there isn't a need to use pens; as pencils work just fine; that there is no need to produce or support pens anywhere -- its preposterous!
