BUILT-IN MATHEMATICA SYMBOL

$NewSymbol

$NewSymbol
is a global variable which, if set, is applied to the name and context of each new symbol that Mathematica creates.

$NewSymbol is applied before the symbol is actually created. If the action of $NewSymbol causes the symbol to be created, perhaps in a different context, then the symbol as created will be the one used.

$NewSymbol is applied even if a symbol has already been created with a Stub attribute by DeclarePackage.

$NewSymbol is not applied to symbols automatically created by scoping constructs such as Module.

Set $NewSymbol to a function that prints the name and context when a new symbol is created:
