> For me it's a 'yes' based on the simple rule that explicit is always better than implicit. That sort of 'optimisation' seems to be really cool when you're just starting out in a language but in the long run it isn't worth it.

I don't really get what you call implicit when you terminate statements with semicolons instead of linebreaks... ... Ok, I get what you're hinting it: there are some (very) few exceptions. However, I cannot see where there is any 'optimisation' in using linebreaks instead of semicolons. You better need to explain why someone should use both linebreaks _and_ semicolons, when only using linebreaks is actually as good as well.

Basically, it's just a matter of style. Aside from a few exceptions (e.g. described in http://inimino.org/~inimino/blog/javascript_semicolons), linebreaks terminate a statement. If you stick with writing only one statement per line, I don't see what's so implicit with it. Rather terminating a statement both with a line break and a semicolon is a tautology, and hence introduces unnecessary redundancy.

The actual question is, whether one can require that developers know the (maybe a handful) exceptions where a line break doesn't terminate a statement. I have decided (for myself) that I can require that knowledge, as it really comes down to only a few exceptions (that I believe are easy to remember).

But, of course, I'm aware that one can also come do another reasonable conclusion.

The only important thing is that people make a concious decision about the issue at all. The importance of this increases with the number of people that are working together on a particular project.

Here a link to another article discussing that issue: http://mislav.uniqpath.com/2010/05/semicolons/

But linebreaks don't terminate statements in javascript.

  x = y
  
  /* TODO: clean this up to make it more readable
   * and maybe add some semicolons
   */
   
  + 4
  
  
... is a single statement.

It's funny how people will take an assumption and keep it without ever verifying if that assumption really holds.

This is a really nice example of that.

It also is reminiscent of one of my favourite programming jokes:

   int x;
   int y;

   x = 0; /* initialise both x 
   y = 0;    and y to 0 */
