I'm pretty sure, that you should use Parrot calling conventions for all subs, the more that subs are objects inside Pie-thon. > print (lambda x: x+1)(0) # prints "1\n" > jsr $I00001 #### :( why can't I "call"?####### The register based j* branches take an absolute address. Imcc has no way to find out where the branch will go in the general case. Using these opcodes is almost unsopported inside imcc. With Parrot calling conventions and an appropriate subroutine object you can achieve the same effect, with additional context saving as needed. While this jump opcode may be needed somewhen (what for? - or even get tossed), all effort currently goes into PCC and optimizing that stuff finally.
