I still wanted to test if that would even work. I confirm it does. Good to know.
>From my perspective:
Con:
* unneeded handling/cost as compared to declaring outside of loop.
* the var can only be used for one pass after which it is reset.
Pro:
* advantage for refactoring and ease of transplantation of code to a new
function.
By the way the following:
var j: string
var j: string
j= "hallo"
echo j
Run
fails to compile with:
Error: redefinition of 'j'; previous declaration here: blabla
