TODO: unresolved issues
text:
"p << end
print me!
end"
symptoms:
not recognized as a heredoc
solution:
there is no way to distinguish perfectly between the << operator and the start
of a heredoc. Currently, we require assignment to recognize a heredoc. More
refinement is possible.
• Heredocs with indented terminators (<<-) are always distinguishable, however.
• Nested heredocs are not really supportable at present
text:
print <<-'THERE'
This is single quoted.
The above used #{Time.now}
THERE
symtoms:
From Programming Ruby p306; should be a non-interpolated heredoc.
text:
"a\332a"
symptoms:
'\332' is not recognized as slash3.. which should be octal 332.
solution:
plain regexp.. should be easy.
text:
val?(a):p(b)
val?'a':'b'
symptoms:
':p' is recognized as a symbol.. its 2 things ':' and 'p'.
:'b' has same problem.
solution:
ternary operator rule, precedence stuff, symbol rule.
but also consider 'a.b?(:c)' ??
