/**
* Make an assertion that `error` is an `Error`.
* If not then an error will be thrown.
* An error class and a string that should be included in the
* error message can also be asserted.
*
* @example Usage
* ```ts no-eval
* import { assertIsError } from "@std/assert/assert-is-error";
*
* assertIsError(null); // Throws
* assertIsError(new RangeError("Out of range")); // Doesn't throw
* assertIsError(new RangeError("Out of range"), SyntaxError); // Throws
* assertIsError(new RangeError("Out of range"), SyntaxError, "Out of range"); // Doesn't throw
* assertIsError(new RangeError("Out of range"), SyntaxError, "Within range"); // Throws
* ```
*
* @typeParam E The type of the error to assert.
* @param error The error to assert.
* @param ErrorClass The optional error class to assert.
* @param msgMatches The optional string or RegExp to assert in the error message.
* @param msg The optional message to display if the assertion fails.
