DynamicModule variables names convention

[kubaPod]

A feature request

While in majority of cases DynamicModule[{x},.. will be typeset to

DynamicModuleBox[{ $CellContext`x$$ }, ...

the majority of users will not know that. So if the UI creator used x the name should remain "x"

But since

• I know one compose DynamicModuleBox manually but I have never heard of it being done.
• One could also do DynamicModule[ { MyPackage`x, x },
• Or authors of w-n-e may want to be strict.

We need to meet middle way.

So I propose the name to be user friendly and trying to match $CellContext`x$$ and friends while fullName being strict full name for an explicit match only and for a full control for edge cases.

Yes, this is a good idea. We will change the behavior as proposed: By default, we will not require an "exact" name match anymore, i.e. implicitly normalize the given variable name (x -> $CellContext`x$$), like it happens behind the scenes for DynamicModule. We will introduce a parameter useExactName (default false) that you can set to true to get the current behavior, for full low-level control (although I don't think that should really be necessary).

This will be in Cloud 1.55.
