It's cheap, but it works.

|
Doesn't handle non-alnum names.
|
|
|
|
Because the strings are parsed at start time, rather than compile time,
|
|
it's basically the same as implementing an inscribe command
|
|
and using it to write a simple Joy script to load the defs:
|
|
|
|
for line in defs:
|
|
print(f'[{line}] inscribe')
|
|
|

Eh?
