D Tokens

[Markus]

Hi, guys!

I would like to ask about D Lexical.

As I understand the D Source Text consists of the following:

*Source Text 
**white spaces 
**end of lines 
**comments 
**tokens 
**special token sequences 
**end of file 

Then, D Tokens consist of the following:

*tokens 
**Identifiers 
**String Literals 
**Character Literals 
**Integer Literals 
**Float Literals 
**Keywords 
**Some Characters

My question is this: 
How do you name those characters (delimiters, operators or somehow else)? I know
that in Ada programming language the following characters are called
“delimiters”:

/
/=
