Rly::Lex
  Simple Lexer
    should have a list of defined tokens
    should output tokens one by one
  Error handling
    raises an error, if there are no suitable tokens
    calls an error function if it is available, which can skip a token
    raises an error, if there is no possible tokens defined
    calls an error function if it is available, which returns a fixed token
  Block-based Token Lexer
    calls a block to further process a token
  Ignores Lexer
    should honour ignores list
  Non-outputtable tokens Lexer
    process but don't output tokens without a name
  Literals Lexer
    should output literal tokens

Rly::Production
  should have a length same as length of its symbols
  should convert to_s as source -> symbols
  should build a list of unique symbols

Rly::Grammar
  requires a list of terminals to be initialized
  should generate parser.out same as Ply does (PENDING: No reason given)
  should reject terminals named in lowercase
  has a default terminal -- error
  precedence
    should allow to set precedence
    should allow setting only :left, :right or :noassoc precedence associations
    should not allow to set precedence after any productions have been added
    should not allow setting precedence several times for same terminal
  LR tables
    builds LR items for grammar
    builds correct FOLLOW table
    sets LR items to correct default values
    builds correct FIRST table
  productions
    should return a Production object when adding production
    should register one-char terminals
    should default precedence to [:right, 0]
    should add production to the list of non-terminals
    should add production number to referenced non-terminals
    should reject productions not named in lowercase
    should add production number to referenced terminals
    should base the precedence on right-most terminal
    should add production to the list of productions
    should reject :error production
    should not allow duplicate rules
    should raise ArgumentError if one-char terminal is not actually an one char
    should add production to the list of productions referenced by names
  start
    should set start symbol if specified explicit
    should add 0 to start rule nonterminals
    should accept only existing non-terminal as a start
    should set start symbol to first production result
    should set zero rule to S' -> :start

Rly::LRTable
  should compute the LR(0) closure operation on I, where I is a set of LR(0) items
  should compute the LR(0) goto function goto(I,X) where I is a set of LR(0) items and X is a grammar symbol
  should compute the LR(0) sets of item function
