This applies to require bareword as well:

$ perl5.15.5 -MO=Concise -e 'require a:: . 1'
7  <@> leave[1 ref] vKP/REFC ->(end)
1     <0> enter ->2
2     <;> nextstate(main 1 -e:1) v:{ ->3
6     <1> require sK/1 ->7
5        <2> concat[t1] sK/2 ->6
3           <$> const[PV "a::b"] s/BARE ->4
4           <$> const[IV 1] s ->5
-e syntax OK

$ perl5.15.5 -MO=Concise -we 'require a::b + 1'
Warning: Use of "require" without parentheses is ambiguous at -e line 1.
syntax error at -e line 1, near "require a::b +"
-e had compilation errors.
