L>NAME
* L>NAME ( lfa -- nfa )

converts a pointer to the link-field (LFA) to point
then to the corresponding name-field (CFA) - this one is one of
the slowest operation available. One should always use the inverse
operation "N>LINK" and cache an older value if that is needed.
Some words might be linked but they do not have a name-field (just
the other fields) but this word can not detect that and will try to look
into the bits of the dictionary anway in the assumption that there is
something - and if done in the wrong place it might even segfault.
Only in fig-mode and for traditional fig-mode programs, this word may
possibly have enough extra assertions to be somewhat reliable.
(and fig-mode did not know about >SYNONYMs - see note at >LINK>).
