incorrect postfix conditionals evaluation

[dreyks]

what <%= 'ever' if true %>

evaluates to an empty string

> eval Erbse::Engine.new.call("what <%= 'ever' if false %>")
 => ""
> Erbse::Parser.new.call("what <%= 'ever' if true %>")
 => [:multi]

==========

<% [].each do %>
  <% next if true %>
<% end %>

produces incorrect ruby syntax

> eval Erbse::Engine.new.call("<% [].each do %>\n<% next if true %>\n<% end %>")
SyntaxError: (eval):3: syntax error, unexpected keyword_end, expecting end-of-input
; end; _buf = _buf.join("".freeze)
     ^

 => [:multi, [:newline], [:block, " next if true ", [:multi, [:newline]]]]

workaround

Erbse::Parser.class_eval do
  remove_const 'BLOCK_EXPR'
  const_set 'BLOCK_EXPR', /^\s*\b(if|unless)\b|\sdo\s*$|\sdo\s+\|/
end
