module Parser
# Context of parsing that is represented by a stack of scopes.

# Supported states:
# + :class - in the class body (class A; end)
# + :module - in the module body (module M; end)
# + :sclass - in the singleton class body (class << obj; end)
# + :def - in the method body (def m; end)
# + :defs - in the singleton method body (def self.m; end)
# + :def_open_args - in the arglist of the method definition
# keep in mind that it's set **only** after reducing the first argument,
# if you need to handle the first argument check `lex_state == expr_fname`
# + :block - in the block body (tap {})
# + :lambda - in the lambda body (-> {})
