Not really. Especially in data binding the & prefix can clearly bind 
data structure to pascal structure.

I am not aware & is an operator in pascal. On the other hand, & is 
exactly for the purpose of escaping identifiers in object pascal. Why do 
you want to use something you come up with (_) instead of what object 
pascal natively offers (&)?

Yes, suffixes like 1, 2, 3... can solve the problem of case-sensitive 
data structure on one side and case-insensitive Pascal code on the other 
side.

Btw. the new Lazarus identifier completion finds identifiers containing 
a phrase as well - it doesn't have to start with it.
