This is the suggested template for new VIPs.

Title: Rename dunder log define function to event.

Type: Standard Track

Simple Summary

Rename __log__ keyword on definition of a event to event keyword instead.

Motivation

As a few users have pointed out, the __log__ keyword in defining an event is not as clear as using event({arg1: int128}) style defintions.

Specification

MyLog: __log__({arg1: indexed(bytes <= 3)})

Becomes

MyLog: event({arg1: indexed(bytes <= 3)})

The emitting of a log event will remain the same:

log.MyLog("123")

Backwards Compatibility

This is not backward compatible (full rename).

Note: the syntax for "emitting"/logging an event is still log.MyLog('arg')

Yes I feel the event / log keyword combination will work well.
