Words containing < and > have presented historical problems, such
as not being able to assign them via >: or quote them with '.
There was also an open question about exactly how many forms of words
would be allowed, when it would come into conflict with TAG!
This commit patches in a self-contained bit of arrow-word code that
lets you build any WORD! you like out of >, <, |, +, -, =.
The only rule is that such words cannot both begin with a < and
end with a >.
A current special exemption is made for <>, which has a concept
for being both a tag and executable that has not yet been done.
See examples in the test The test also exercises transcoding of the SET-WORD!, GET-WORD!, SYM-WORD!, QUOTED! variants, as well as being bumped up against the edges of a block or path.
