I stumbled on a minor (?) `⍕` problem
I `)dump`ed the results of a previous work (content irrelevant. Restore it, and
examine these results :
```
)load Exp01dmp.apl
DUMPED 2023-05-27 22:12:26 (GMT+2)
⍴bar
500 3
```
A bit too large ; sample it :
```
⍴sample←2↑[1]bar
2 3
```
It's a vanilla numeric matrix :
```
26⎕CR sample
16 32 32 16 32 32
sample
142 1.375974377E¯13 0.264
53 5.267033354E¯14 0.008
```
It seems that trying to format it *fails!* This :
```
test←4 0 7 ¯3 7 ¯4⍕sample
```
**never** returns, and the `apl` process eats 100% of the time of one of my
8-core CPU. The only way to exit is to kill the `emacs` buffer where it runs :
`emacs` asks for permission to kill the process (see below).
Setup : Laptop : core i7, 16 GB RAM, Debian testing, `apl_1.8-1_amd64.deb`
downloaded from the Gnu mirror. APL runs from `emacs` via the `inferior-mode`
created by `gnu-apl` (from the `gnu-apl-mode` package).
HTH,
