Recently, I was surprised by the fact that it is not possible to create a table, where the values of entries are tables.

Toy example:

T1:=table(["1"=table(["first"=12, "second"=15]), "2"= table(["first"=9, "second"=7])]);

The code

T1["1"];

doesn't return table(["first"=12, "second"=15])

If table has lists in right-hand side

T1:=table(["1"=[12, 15], "2"= [9, 7]]);

all works properly.

I need to use a procedure where one of the parameters is a function. Conceptually, this seems straightforward, but I’m encountering unexpected behavior. Here’s a minimal example of my approach:

f1:=proc(t::numeric, fn::function)::numeric;
return fn(t+1)+1
end proc;

However, none of the following calls return the correct result:

f1(2, sin);
f1(2, sin());
f1(2, sin(x));
f1(2, u-> u^2);

Any guidance would be greatly appreciated!

It is very strange, but I cannot find in v. 2025 shortcut or a button for stoping current evaluation.

I had no problem with this in previous version, but now the absence of immediate stoping make troubles for me,

Here is a toy example

L:=<<1 | 2 | 3>; <4 | 5 | 6>>; 
(L[1,2], L[2,3]):=(0 $ 2):

As expected, L now equals <<1 | 0 | 3>; <4 | 5 | 0>>

Now I want to make a bulk assigment with the use of seq operator

(seq('L'[q,  q+1] , q=1..2)) := (0 $ 2);

but it fails. Nevertheless

seq('L'[q,  q+1] , q=1..2)

works as needed and returns unevaluated L[1,2], L[2,3]

Maple has powerful tools to manager styles of its documents. Similar to word processors, it is possible to set up font and paragraph options. Unfortunately, the styles of Help System, as I understand, are completely unchangeable. Meanwhile, it makes sense to improve the view of Help pages. Say, Help’s hyperlinks are pale and unpleasant  for eyes. Maybe, are there some hidden options for changing Help styles?
