Added commands:
/entityify []
Summons a falling block entity with no gravity and same blockstate as block pos at pos. If removeBlock exists and is true, removes the block as well.
/for
for(int varname=start;varname<end;varname+=increment)
runs command with all instances of $(varname) replaced with the value in that loop. Example:
/for i 0 10 1 tell @a Loop Iteration $(i)
would tell all players
Loop Iteration 0
Loop Iteration 1
Loop Iteration 2
Loop Iteration 3
Loop Iteration 4
Loop Iteration 5
Loop Iteration 6
Loop Iteration 7
Loop Iteration 8
Loop Iteration 9
/for loops can be nested!
