I never change BASE and allow source-code to be interpreted. The only exception is when I have a section of source-code that contains only constants all of which are in a different base. I change BASE for that section only. This may be a table of constants being comma'd into an array, or it may be a series of CONSTANT definitions. It would almost never include colon words or other Forth code.

So, I disagree with Raimond --- I wouldn't outlaw the use of a different BASE for input --- I would just advise the user to do this only for sections of source-code that contain only constants, but not do this for source-code that contains code. 

There are a lot of things that are a bad idea, but shouldn't necessarily be outlawed --- in the real world, we have the marijuana issue --- I think that outlawing mota is a big mistake, but I also advise people to not smoke mota or at least to do so only in moderation.

The subject of changing BASE for input was discussed already here:
