+/**
+ * `tryCatch` takes two functions, a `tryer` and a `catcher`. The returned
+ * function evaluates the `tryer`; if it does not throw, it simply returns the
+ * result. If the `tryer` *does* throw, the returned function evaluates the
+ * `catcher` function and returns its result. Note that for effective
+ * composition with this function, both the `tryer` and `catcher` functions
+ * must return the same type of results.
+ *

+ * @since v0.20.0

+ * @sig (...x -> a) -> ((e, ...x) -> a) -> (...x -> a)
+ * @param {Function} tryer The function that may throw.
+ * @param {Function} catcher The function that will be evaluated if `tryer` throws.
+ * @return {Function} A new function that will catch exceptions and send then to the catcher.
+ * @example
+ *
+ *      R.tryCatch(R.prop('x'), R.F)({x: true}); //=> true
+ *      R.tryCatch(() => { throw 'foo'}, R.always('catched'))('bar') // => 'catched'
+ *      R.tryCatch(R.times(R.identity), R.always([]))('s') // => []
+ *      R.tryCatch(() => { throw 'this is not a valid value'}, (err, value)=>({error : err,  value }))('bar') // => {'error': 'this is not a valid value', 'value': 'bar'}
