Oleg, your Compact Verb Definitions (link below) is really impressive. Do you have an entry for
its utilities dltb and strsplit?

To chime in on this, there is Phrases page
http://www.jsoftware.com/jwiki/Phrases/Definitions
that allows to lay out definitions like this:
'Arithmetic' defn
add=: : x+y NB. addition
pow=: ^y : x ^ y NB. power
sqr=: y pow 2
sqrt=: y pow 0.5
)
It was inspired by APL defn mode. Note how it uses : introduce
dyadic and ambivalent verbs.
From: Kip Murray <[EMAIL PROTECTED]>
I like adverbs fn and op for defining one-line functions and operations:
fn =: 3 : NB. for one-line monadic verbs = functions
'1%y' fn 5
0.2
op =: 4 : NB. for one-line dyadic verbs = operations
3 'x%y' op 4
0.75
You can read '1%y' fn as "1 divided by y function" and
'x%y' op as "x divided by y operation". The notation focuses
attention immediately on the calculation.
You can do
f =: ('1%y';':';'x%y') fn
f 5
0.2
3 f 4
0.75
but if your aim is easy comprehension,
f =: verb define
1%y
:
x%y
)
NB. that is,
f
3 : 0
1%y
:
x%y
)
is better.
