The Jolly Beggar was published in Herd's "Scots Songs" in 1776, 41 years before Byron's letter, and goes partially
LL grammar LL("m") grammar for some "m". A "ε"-free LL(1) grammar is also a SLR(1) grammar. A LL(1) grammar with symbols that have both empty and non-empty derivations is also a LALR(1) grammar. A LL(1) grammar with symbols that have only the empty derivation may or may not be LALR(1). LL grammars cannot have rules containing left recursion. Removing left recursion from a context-free grammar is always possible. However, the resulting grammar may be bigger, require more lookahead tokens than preferred to be an LL grammar, or not be an LL grammar at all. LL("k") grammars that are ε-free can be transformed
