Eval returns the value of this Expr in the environment env.

!- !+comparison Equal reports whether x and y are deeply equal. !-comparison Map keys are always compared with ==, not deeply. (This matters for keys

Check reports errors in this Expr and adds its Vars to the set.

Work runs the simulation 'runs' times.

!-lexer The read function is a decoder for a small subset of well-formed S-expressions. For brevity of our example, it takes many dubious shortcuts.

IsPalindrome reports whether s reads the same forward and backward. (Our first attempt.)

IsPalindrome reports whether s reads the same forward and backward. Letter case is ignored, as are non-letters.

!+rev reverse reverses a slice of ints in place.

describe returns a string describing the current token, for use in errors.

work blocks the calling goroutine for a period of time that is normally distributed around d with a standard deviation of stddev.

!-write !+close Close flushes the compressed data and closes the stream. It does not close the underlying io.Writer.

Has reports whether the set contains the non-negative value x.
