Nested 'for' loops in native Google Sheets (no scripts) - loops

Question

I'm aware that it's possible to emulate a for loop in Google Sheets via the following:
=ARRAYFORMULA(IF(LEN({range_0 to iterate over}),{function_0 for each element in range_0}))
I've not been able to expand on the above approach to achieve the effect of a multi nested for loop. Is this possible? Ideally this would look something like:
=ARRAYFORMULA(IF(LEN({range_0 to iterate over}),IF(LEN({range_0.1 to iterate over for each parent element in range_0}),{function_0.1 for each element in range_0.1},{OPTIONAL: function_0 for each element in range_0})))
Example application:
Iterating over each cell in a row for each row in a column (see below; I'm sure there are ways to achieve this effect via other methods, but I have use for the requested and specified method for cases where a single dynamic formula is necessary to keep up with an unknown and changing number of rows, columns, and functions involved):
Raw data:
Thing
Type
Feature
Cost
Apple
Fruit
Seeds
$1
Car
Automobile
Wheels
$6,000
Laptop
Computer
Keyboard
$500
Grape
Fruit
Tastiness
$0.50
Theoretical formula:
=ARRAYFORMULA(IF(LEN(`Thing`),IF(LEN(COLUMNS({current row of `Thing`})),{current cell in current row of `Thing`} & " of column " & COLUMN({*current cell*}) & " and row " & ROW(`Thing`),""),""))
Output of above theoretical formula:
Thing
Type
Feature
Cost
Apple of column 1 and row 3
Fruit of column 2 and row 3
Seeds of column 3 and row 3
$1 of column 4 and row 3
Car of column 1 and row 4
Automobile of column 2 and row 4
Wheels of column 3 and row 4
$6,000 of column 4 and row 4
Laptop of column 1 and row 5
Computer of column 2 and row 5
Keyboard of column 3 and row 5
$500 of column 4 and row 5
Grape of column 1 and row 6
Fruit of column 2 and row 6
Tastiness of column 3 and row 6
$0.50 of column 4 and row 6
Thank you for your help!

Answer 1

try:
=ARRAYFORMULA(IF(LEN(A3:E7), A3:E7&" of column "&COLUMN(A3:E7)&" and row "&ROW(A3:E7), ))
