pop_parent_expression()

Replaces the current parent expression with the one found on the top of the previous parent expression stack (pop).

354:                 end
push_parent_expression(exp)

puts the current parent expression on top of the ‘previous parent expressions’ stack, the current parent expression is replaced with the supplied parent expression.
