We are talking about computer semantics which exist in a discretized world, not english language semantics. By your logic, the word integer would be any number not a fraction or decimal down to negative infinity up unto positive infinity. There is no concept of infinity on a computer.

Anyways, that's besides the point, and I think you missed the meaning behind my comment.

The reason why a tab space cannot semantically mean indentation in our world, is because nobody can agree on what that indentation should be. Since you are old enough to have owned a typewriter, maybe you are old enough to remember that by legacy, a tab was equivalent to exactly 8 spaces, and much of our software that runs the internet makes that assumption. Now however, people are saying "use tab to mean indent and everyone can have their way" To quote mikko, "There is no style guide or coding conventions saying that the tab character should be the indent. This assumption is easy to make because it allows you to stick your head into the sand, ignore the surrounding world and by singing “let the users pick their own tab width” mantra."

Again, this wasn't to start a tab vs spaces war for go, and why go chose tabs. It's fine to make a choice, but it was your second statement that provoked my comment.

I get what you mean but a tab is purposely meaningless and unqualified.

It means 1 indent, not 8 spaces, 3 bananas or one tree. It is a unit. How the user displays that is up to them.

This. Absolutely this.

I used to hate tabs and want 2 spaces only, until I started working with other developers. Then suddenly tabs made sense, especially when you've got IDEs coercing every edited file to a person's indentation standard. Standardize on the tab and the pain goes away.

Sure there is: http://en.wikipedia.org/wiki/IEEE_754-1985#Positive_and_nega...

Ok sorry. There is no true representation of infinity.

Semantics is contingent upon meaning. Meaning varies and changes. Meaning is defined over time. That's the case with most words. In formatting text, it's as semantic to say that tabs are for "tabulation" and "indentation" as much as spaces are for "space" and "spacing characters." Tabs have always been semantically better as indentation in computing.
