Improve execute if data

So, now execute if data only has one use: checking if NBT tag exists, and thats useful, but not that much.

Here is my idea of improving it:

You can check if NBT tag exists(or has a value) like previously:

/execute if data entity @s SelectedItem.id exists

But you can also compare the value(or lenght for lists) to something else:

Score:

/execute if data entity @s SelectedItem.Count matches score @s testscore

The above checks if the NBT tag 'SelectedItem.Count' of @s matches the score 'testscore' of @s

Entity(like data store entity):

/execute if data entity @s SelectedItem.id matches entity @p Inventory[10].id

The above checks if the NBT tag 'SelectedItem.id' of @s matches the NBT tag 'Inventory[10].id' of @p

Tag(can be ANY tag):

/execute if data entity @s SelectedItem.id matches tag #minecraft:fishes 

The above checks if the NBT tag 'SelectedItem.id' of @s matches any of the id's specified in the tag '#minecraft:fishes'

This would greatly improve the execute if data command and would make the item tags not that useless anymore and strings in nbt could be compared better.

I got kind of inspíred by https://feedback.minecraft.net/hc/en-us/community/posts/360029482531--18W44A-Executing-if-unless-Match-Data?input_string=Improve%20execute%20if

But i wanted to add things

  Please don't forget

  matches X

  where X is a double. This way, you don't need a scoreboard to test for fixed numbers.

  Expecially needed for storing and reading the result of a command with

  /execute store success storage ...
  &
  /execute if data storage ...

  If you try checking with the second command, it can't differentiate whether the first command failed or not! In both cases it stores a value, but that value is not checked.

  Turns out, you actually can test whether the nbt data matches a pre-determined value. It's not as versatile as what you're suggesting, but at least we have a workaround for now.

  You just need to use the standard nbt syntax and it will check if the data matches:

  /execute if data entity @s {SelectedItem:{Count:1b}}

  Which would almost work like your example:

  /execute if data entity @s SelectedItem.Count matches score @s testscore

  matches tag doesn't really make sense, how would the game know what kind of tag to use?
