by_symbol

Splits a string to individual symbols and then applies the parser <code>p</code> to the
resulting character vector, otherwise the parser fails. If <code>finish = TRUE</code>
then the parser should completely consume its input. If <code>finish = FALSE</code>
then any remaining part of the string is discarded.
This function is identical to <code>by_split(p, "", finish)</code>.

Construct parser combinator functions, higher order functions that
parse input. Construction of such parsers is transparent and easy. Their main
application is the parsing of structured text files like those generated by
laboratory instruments. Based on a paper by Hutton (1992)
<doi:10.1017/S0956796800000411>.
