ipython is not showing the pretty printing by default

[Roger-luo]

I feel this isn't nice UX. What is currently printed as default has little information about the program being defined. And I cannot find ANY method in the hint to pretty print the program. I think we discussed this somewhere, but I cannot find the issue/PR anymore.

this is what you get currently

In [29]: prog
Out[29]: <bloqade.builder.assign.Assign at 0x302fbf800>

I have to press many buttons to go back and write print(prog) to see what's in prog
