annotate libinterp/parse-tree/pt-colon.h @ 24362:3fc24b792a24

avoid including symtab.h, symscope.h, or symrec.h unnecessarily * main-window.cc, workspace-view.cc, call-stack.cc, call-stack.h, defun-int.h, input.cc, load-save.h, symscope.h, symtab.h, variables.h, ov-fcn-inline.h, ov-fcn.h, ov-usr-fcn.cc, ov-usr-fcn.h, lex.h, oct-lvalue.h, parse.h, pt-arg-list.h, pt-array-list.h, pt-assign.h, pt-binop.h, pt-cbinop.h, pt-cell.h, pt-cmd.h, pt-colon.h, pt-const.h, pt-decl.h, pt-eval.h, pt-except.h, pt-exp.h, pt-fcn-handle.h, pt-idx.h, pt-jit.h, pt-jump.h, pt-loop.h, pt-mat.h, pt-misc.h, pt-select.h, pt-stmt.h, pt-unop.h, token.cc, token.h: Where possible, use forward declarations for symbol_table, symbol_scope, and symbol_record. Don't include symtab.h, symscope.h, or symrec.h unless needed. Use symbol_record::context_id instead of symbol_table::context_id or symbol_scope::context_id. Delete typedefs for symbol_table::context_id and symbol_scope::context_id.
