| Platform | All | Severity | minor | Priority | normal |
| Summary | Different treatment of < > in refinements vs. words |
|---|---|
| Description |
Further to #1302, please note the examples. The ones for > are similar (but not exactly equal). Wouldn't it be better to decree: no <=> in any-word! literals except a limited list, viz. the ones needed as operators (you can reserve a few for future extensions). |
| Example code |
>> type? quote a< ** Script error: < is missing its value2 argument >> type? quote /a< == refinement! >> type? quote < == word! >> type? quote /< ** Script error: < is missing its value2 argument |

See http://www.rebol.net/r3blogs/0305.html
Note that because word is allowed, we allow /word, which also means / is allowed so also / |

Note: The special-case words that have < or > in them can't be used directly in literal refinement syntax, but can be converted to refinements (that won't load properly) using TO-REFINEMENT.
>> to-refinement quote <> == /<> >> type? quote /<> ** Syntax error: invalid "refine" -- "/<" ** Near: (line 1) to-refinement quote /<> The special case of words containing only the / character (perhaps repeated) are always interpreted as a word! when loaded, not a refinement, but can be converted to refinements (that won't be interpreted as being refinements by LOAD) using TO-REFINEMENT. >> to-refinement quote / == // >> to-refinement quote // == /// >> to-refinement quote /// == //// >> type? quote /// == word! >> type? quote //////// == word! |
