Agreed. I was very impressed Mark Wieder implemented that as quickly as
he did - thanks Mark!

@mwieder: Thanks for your contribution. Unfortunately, though, we don't
feel it is an appropriate addition to the LiveCode language.
In the interests of completeness, maybe it would be helpful to quote the
comment [1] fully:

The addition of synonyms to the language has been discussed at length in the
past, and the general consensus has been that it is better that the core
language have one way of naming each thing rather than a multitude.
We don't see that adding "!=" and "!" to the language solves any real problem. Indeed, we already have "<>" as a
synonym for "is not" which is a widely established symbol for the given operator. At the end of the day, each programming language chooses its
own set of symbols for the common operators - for example, C also has "==" for equality, LiveCode has "is" or "=".
In the future, Open Language will allow people to add their own sets of
operators which appeal to their personal taste but in a fashion which is far
more modular. We feel that that would be the correct time to experiment with
such language additions rather than overloading the core with synonyms.
