I can't find a case where where "or" is ambiguous. "or" can't currently
follow a regex delimiter or modifier.
>perl -e"//or 1"
Bareword found where operator expected at -e line 1, near "//or"
(Missing operator before r?)
Number found where operator expected at -e line 1, near "r 1"
(Do you need to predeclare r?)
syntax error at -e line 1, near "//or "
Execution of -e aborted due to compilation errors.
>perl -e"//oor 1"
Bareword found where operator expected at -e line 1, near "//oor"
(Missing operator before r?)
Number found where operator expected at -e line 1, near "r 1"
(Do you need to predeclare r?)
syntax error at -e line 1, near "//oor "
Execution of -e aborted due to compilation errors.
>perl -e"//omor 1"
Bareword found where operator expected at -e line 1, near "//omor"
(Missing operator before r?)

syntax error at -e line 1, near "//omor "
Execution of -e aborted due to compilation errors.
>perl -e"//olor 1"
Bareword found where operator expected at -e line 1, near "//olor"
(Missing operator before lor?)
Number found where operator expected at -e line 1, near "lor 1"
(Do you need to predeclare lor?)
syntax error at -e line 1, near "//olor "
Execution of -e aborted due to compilation errors.
