Research direction
Read example 4 in docs/HowItWorks.md first, then trace how the parser handles $a == $b = $c and the constraint that an assignment's left-hand side must be a variable. Done means the expression is represented as $a == ($b = $c) rather than ($a == $b) = $c.
Written by the indexing model from the issue text.
Description
Noticed while looking at example 4:
In PHP an expression like $a == $b = $c is parsed as $a == ($b = $c), because this is the only valid way to parse the code under the constraint that the LHS of an assignment must be a variable. The parser currently treats this as ($a == $b) = $c instead.
