Casting between structures is no longer admitted?

[giovi61]

Hello to everyone,

I have encountered problems with the code written before the build versione 1599 of Mediaeditor. The code for casting between structures is no longer accepted.

What I'm saying is verifed. I still have a version of Metaeditor build 1562 and if I compile the following code is regularly compiled:

struct str1
  {
   long    l;
  };

struct str2
  {
   int     low_part;
   int     high_part;
  };

void OnStart()
  {
    str1 s1;
    str2 s2;

    s1.l = 256;
    s2= (str2) s1; //This is compiled without any problems
    
    s2= s1;        //This is compiled but with implicit casting notification
 } 

By compiling the same code with the updated versione of the metaeditor (build 1599) I get this error message:

s2=s1; //cannot cast 'str1' to 'str2'   

s2=(str2) s1; //'=' - illegal operation use

Now I would like to see if this is a bug for the metatrader or it was decided to implement a different casting form, especially for Union operations between structures that were not explicitly contemplated but could be realized as described in this documentation:
https://docs.mql4.com/basis/types/casting

Personally I need this feature on indicators that are very important to me

Do you know anything about it?
