how would you feel if ...

how would you feel if Python's assignment operator was := instead of just = ?

I won't feel any change, because of some relativistic effects during time travel.

I use from the IEC 61131-3 standard the Structured Text. The syntax is similar to Pascal, and it's not vendor-specific.

The:= is used for assignment. A plain colon is followed by a datatype and comparison is made with =.

I don't have bad feelings to write := and if Python had this instead of =, I think we won't recognize it or talk much about it.

Changing this decision afterwards without breaking all existing code is nearly impossible.
