Introduction

• Language Designers:

  Looking for operator or function names? Well have a look at the following and remember using existing one may ease the transition :)

• Language Users:

  You know one language and want to find the corresponding operator or function in another language

• Language lovers:

  Want to know the various ways people invented for commenting/assigning/...?

This is of course incomplete. I welcome contributions!

You may also have a look at this information sorted by languages.
