Practical parser notes from the grammar

The grammar includes explicit ambiguity guidance for parser implementation:
  • record declarations vs record expressions
  • generic arguments vs comparison operators
  • newline-sensitive list separators
  • is pattern checks at comparison precedence
  • fallible binding (pattern <- expression) as statement-level syntax
  • pipeline lowering behavior (|>)
