Don't suggest adding `let` in certain `if` conditions Avoid being too eager to suggest `let` in an `if` condition with an `=`, namely when the LHS of the `=` isn't even valid as a pattern (to a first degree approximation). This heustic I came up with kinda sucks. Let me know if it needs to be refined. |

– that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).
For more information about how these things work in rustc, see the rustc dev guide:
