Please provide symbol lookup for the identifiers used amongst `syn match`, `syn region`, and `syn cluster`.

[egberts]

Often times, the syntax spec file (ones in the .vim/syntax directory, have hundreds, if not thousands of identifiers.

And having the support of the symbol table would greatly cut down lookup efforts (instead of currently doing the selection-word, cut-n-paste into a search bar).

The symbol definition of such identifiers are defined in:

syntax match this_symbol_name ...
syntax region this_symbol_name ...
syntax cluster this_cluster_symbol_name ...

And are easily referenced after keywords like:

\ contains=this_symbol_name[,next_symbol_name ...]
\ contains=@this_cluster_symbol_name[,next_symbol_name ...]
\ nextgroup=this_symbol_name[,next_symbol_name ...]
\ containedby=this_symbol_name[,next_symbol_name ...]

Support for this will greatly assist the large data science community with easier and even simplistic syntax highlight used against high-speed data streaming outputs.
