Important Question on DRAW Dialect Invalid Words
Now that the DRAW dialect uses REDUCE/only, you can write code like this:
view layout [bx: box effect [draw [pen red line 0x0 bx/size]]]
Here the word RED and path BX/SIZE are looked up from the REBOL context during the evaluation of the DRAW dialect.
However, a new issue arises. What if the DRAW block contains an invalid word:
view layout [bx: box effect [draw [pen red print 123 line 0x0 bx/size]]]
The word PRINT is not part of the DRAW block vocabulary, and it is a REBOL functional datatype - so an error results (a rule of REDUCE/only):
** Script Error: Invalid argument: print ** Where: view ** Near: print 123 line 0x0 bx/size
In older versions, the PRINT would be ignored.
Which do you think is better? Let me know what you think on the REBOL2 AltME world.
