    • symbol table: Where a compiler remembers symbols. A program like Perl must somehow remember all the names of all the variables, filehandles, and subroutines you've used. It does this by placing the names in a symbol table, which is implemented in Perl using a hash table. There is a separate symbol table for each package, to give each package its own namespace.
