NAME

       "Devel::MAT::Tool::Reachability" - analyse how SVs are reachable

DESCRIPTION

       This "Devel::MAT" tool determines which SVs are reachable via any known roots and which
       are not. For reachable SVs, they are classified into several broad categories:

       • SVs that directly make up the symbol table.

       • SVs that form the padlist of functions or store the names of lexical variables.

       • SVs that hold the value of lexical variables.

       • User data stored in package globals, lexical variables, or referenced recursively via
         structures stored in them.

       • Miscellaneous other SVs that are used to implement the internals of the interpreter.

SV METHODS

       This tool adds the following SV methods.

   reachable
          $r = $sv->reachable

       Returns true if the SV is reachable from a known root.
