probe/dump - longer to type. when i debug i want it short. even shorter than
probe. ?? most of the time. How about a name similar to that? but 'dump would
work.

how about:
help probe ->>
"Prints a molded, unevaluated value and returns the same value. similar: ? ??
dump"
Also
!>>help dump
Found these words:
dump-face function! Print face info for entire pane. (for debugging)
dump-obj function! Returns a block of information about an object.
dump-pane function! Print face info for entire pane. (for debugging)
there is a convention to call such functions dump-*. that the integrator is
called 'dump makes sense.

that can be done with a naming-convention too. because "help round-" would do
a "wildcard-search". In case of 'round i prefer refinements. In case of 'dump
i would prefer lots of dump-* and dump with a switch. because then its most
easy to add new dumpers. We could even have some support to add new dumpers
on the fly, like
add-dump ['my-type = val/type][dump-my-type]
Now instead of "send" i could not resist to press "hack", and here is:
;the code
dumpers: copy[]
add-dump: func[guard dump-how][
insert dumpers reduce[guard dump-how]
]
dump: func[val][
bind dumpers 'val
foreach[guard dump-how] dumpers [
if attempt guard [attempt dump-how break]
]
:val
]
add-dump [true][probe val]
;demo, dumping an object smart
ctx: context[type: 'my-type id: 1 lots-of-data: [1 2 3]]
dump 1
dump ctx
add-dump ['my-type = val/type][
print ["my-type" val/id "has" length? val/lots-of-data "elements"]
]
dump 1
dump ctx
;demo-output
;first unsmart
1
make object! [
type: 'my-type
id: 1
lots-of-data: [1 2 3]
]
;now smarter
1
my-type 1 has 3 elements
