This has been discussed at length in 2009. TLDR: It's not worth it.

Not worth it. Gripes about semicolons are a symptom of only seeing the superficial and not really understanding enough about languages to see what really is and isn't important. It's like dumping someone because you don't like the color of a dress they wore. Superficial, shallow, inconsequential bikeshed bullcrap, not even worth debating.

why?
groovy, for e.g., is ok without semicolons and with semicolons.
if there is a question of backward compatibility, is it possible to support semicolons?

Can you give a strong technical argument why we should get rid of the semicolons?  I personally quite like them, as do others, so I don't think "I don't like the looks of them" is a strong argument.  What would the language gain by losing the semi-colons.

because a programmer will have a choice of writing or not semicolons, as one anyway presses "Enter" why not to use it as a line separator, and one who likes to type semicolons won't be confused if there is backward compatibility

Thank you for repeating my point, that you have to look at the grammar to see where a semicolon could appear and not just insert a semicolon at every newline.

Sounds reasonable. So it's not likely to be a huge problem except for existing code.

That's okay for reading code that you know compiles, not so great for writing code that might have a missing semicolon.

What if the OP wrote a compiler that turned his version of D sans semicolons into proper D code?

Someone did that with python-style syntax a while back, in the D1 days, though I forget the name of it.

Multiple syntaxes for the same language is kind of cool.

Another reason not listed in previous answers (or I didn't see it) is that D as a unique (AFAIK) capability: string mixins. If the language were whitespace-sensitive (as Python is), writing string mixins would be a lot more painful, as it is very difficult and unconvenient to write the mixed-in strings with correct indentation and line breaks. Having explicit delimiters (both semicolons and curly braces) is very important for the usability of this feature.

i didn't try to implement it myself, but i will try
