Completion after [ does not work in both RelineInputMethod(default) and ReadlineInputMethod(irb --nomuliline).

Other symbols that make completion fail:

[RUBY_VER
+RUBY_VER
-RUBY_VER
puts(*RUBY_VER
1/RUBY_VER
s%RUBY_VER
!RUBY_VER
~RUBY_VER
p(1,RUBY_VER
1?RUBY_VER
1?2:RUBY_VER

Also note that the experimental type completor irb --type-completor can complete these.
