For programmers, it is quite common to use the name of a macro (for instance `foo' for the macro \foo, in other words, the letters f, o, and o). For this purpose, it is customary to call \string which does this sort of things... except that it prepends the escape character, controlled by the counter \escapechar, in front of the name. The traditional way of getting rid of it, is to set \escapechar to -1 (without forgetting to restore the proper value at the end of the process) or to make use of \@gobble. The former has the drawback not to be expandible while the second isn't completely reliable. Here we extend the expandible methods to make it reliable.
