... You're right: destructors are not called in C++ functions that are terminated prematurely, such as with Io's exceptions (based on coros). But, at the...
Attached is some Io code for a text alignment method for Sequence. If passed to a sequence, it will align it based on input, padding with spaces, or if a third...
Quag just pointed out on IRC one problem with this; stripping self before padding. Attached is a new patch which doesn't do this. If you want to strip it, do...

Thomas, Which compiler are you using? You might try removing "--param max-inline-insns-single=500" from vm/base/Makefile. Also, if you aren't running MacOS X,...

I discovered Io a couple days ago and it's an exciting language. I did find one little bug: Io version 20051017 Io> 2^3^2 ==> 64 That should be 2^(3^2)=512. I...
... IOTOKEN_NAME(m)[0] == '^') But operators like ^++$ mean that my solution is not actually correct :-( It passed all the unit tests though, honest. Maybe...
