Hi Jose!
Thank you for your interest in my program.
I do not know if there exists a tacit version of (13 :'x H. y 2') .
I do not share your allergy against
[:-1e_7+] NB. 10 characters
as opposed to
-@:(1e_7+]) NB. 12 characters
Normally I would prefer the shorter version.

Your version would be a neat tacit rewriting of ms, except that you defined
H2 explicitly. The hybrid nature of ms, written this way, is apparent when
one tries to fix it,
ms f.
[: (([: <: {.) ,: [: %: {. * ([: +: {:) - [: >: {.) 2 %~/\ (1 2 3 ,&>/ [: -
[) 4 : '(x H.y)2'"1 [: - 9.9999999999999995e_8 + ]
Personally, I am allergic to forks with leading caps; but finding a remedy
a remedy is easy,
ms=. (<:@:{. ,: %:@:({. * +:@:{: - >:@:{.))@:(2 %~/\ (1 2 3 ,&>/ -@:[)
H2"1 -@:(1e_7 + ]))
Either way, the tricky part is to rewrite H2 tacitly.

Exercise 8. Rewrite the verb explicit verb ms shown below tacitly, as
usual, bonus points for a fixed tacit version (see the message [0]).

A (wicked) solution follows after the warning.

The following is a slightly edited session:

First, the explicit version,

M=: 13 :'|:y Mn 1 2 3,&>/-i.1+y'

Next, the tacit (fixed) version.
Running the J Wicket Toolkit (see the trailing message),

which is need it to define Mnt,

NB. It is fixed...
