// IMPORTANT NOTE:
// The grammar consists of a few LALR(1) conflicts. These issues are, however, correctly handled, due to the fact that the grammar
// is defined in a specific order making the already added parser actions have precedence over the other.
//
// Known conflicts that are correctly handled:
//
// - ELSE: Shift/Reduce conflict Dangling ELSE problem. Lots of articles are around on the internet.
// The shift action is taken here.
//
// - CLOSE_PARENS: Shift/Reduce conflict. This is due to the fact that the explicit cast expression is like the parenthesized
// expression. The shift action is taken here.
//
// - STAR: Reduce/Reduce conflict, between VariableType -> TypeNameExpression and PrimaryExpression -> TypeNameExpression,
// due to the fact variable types can have '*', and look therefore like a binary operator expression.
// The first reduce action is taken here.
