Even in a standard function your code crash. Definitely a problem somewhere.

Hi Emmanuel,
thanks. fixed in *SVN 1709*.

It is indeed fixed. Thanks !
But now I have a question about a subtle difference between niladic
"traditional" function and niladic "inline" functions. What is the
right channel to ask ?

Hi Emmanuel,
feel free post all your concerns to bug-apl@gnu.org. Sometimes
a true APL specialist (which I am not) on the list responds, and
sometimes myself (for more implementation related issues).
The members on the list are generally friendly and helpful.
Best Regards,

Dear list,
It seems that niladic lambdas are treated like constants.
Rough and naïve illustration : pasting this :
```
⍝ What about niladic functions and lambdas ?
⍝ Example of a numeric timestamp generator
⍝ Simplifying assumptions : we want to measure about a few minutes
⍝ and not around midni
FWIW, running the same code in a Dyalog APL Jupyter notebook gives similar
results :
Quid des fonctions et lambdas dyadiques ?

In GNU APL lambda is dyadic if it contains a reference to ⍺ or monadic if
it uses ⍵. There is no way to distinguish a call of niladic lambda from a
definition of niladic lambda in
Hi Emmanuel,
first of all, lambdas are a bad construct which causes quite
a number of syntactic inconsistencies. Simply speaking,
the concept has not been thought out well.
1. A defined function created with ∇ or ⎕FX is unambiguously
that: a defined function. For that reason I sometimes call
th
You note an inconsistency, but the problem isn't worth the lambda syntax
but rather with assignment. In the lambda syntax of Dyalog, the left arrow
are used both to assign functions as well as values, which makes the
evaluation rules complicated.
I came across the same problem when I implemented i
