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.

   $r = $sv->reachable;
