How do I....

[Will Coleda]

Going through my todo (hurm, should make TODO) list for Tcl, I'm 
wondering:

- There's a sprintf opcode. Is there a way to do a scanf?

- is there an ETA on rx_compile? I hesitate to write my own RE compiler 
having already dealt with tcl and tcl's [expr] ^_^

- Did exception handling ever get fixed? (I had submitted a test case 
ages past - Last I saw was Leo saying "patches welcome". It was a COW 
bug, IIRC.)

- Unicode?

- I was told ages past that I should use "global" for tcl's global 
variables to play nice with others... What is the "right" way to store 
my interpreter's global state, then? (for example, I have a global 
PerlHash that maps command names to the builtin functions). I suppose I 
could create my own pad, or even an object... but then how do I access 
it without storing it in a global?
