That's cool. Thanks. I notice it works on numbers and string literals:

"hello".WHAT   # Str()
3.WHAT         # Int()
3.3.WHAT       # Rat()
pi.WHAT        # Num()
(1+3i).WHAT    # Complex()

But it seems to give very inconsistent results when applied to functions:

print.WHAT  # Bool()
say.WHAT    # [blank]
sin.WHAT    # [error]

What is TTIAR?
