`cond` with internal definitions is preferred over `if` with `let`, to reduce nesting

This `match` expression can be simplified using `match-define`.

This use of `format` does nothing.

Using `cond` instead of `if` here makes `begin` unnecessary

This conditional expression can be replaced with a simpler, equivalent expression.

The `begin0` in this definition can be extracted into the surrounding definition context.

The `define` form supports a shorthand for defining functions.

This `map` operation can be replaced with a `for/list` loop.

The `syntax-disarm` function is a legacy function that does nothing.

This expression is equivalent to calling the `positive?` predicate.

This use of `define-values` is unnecessary.

Use the `#:unless` keyword instead of `unless` to reduce loop body indentation.

Use the `#:when` keyword instead of `when` to reduce loop body indentation.

This `and` expression can be turned into a clause of the inner `match` expression, reducing nesting.

This `begin` form can be flattened into the surrounding definition context.

This negated `when` expression can be replaced by an `unless` expression.
