So far it's ok - the language is simple enough, and I can make it do the bits and pieces I want so far. The main thing I miss is static typing and intellisense - everything takes so long when I have to keep looking up help files rather than having intellisense present me with a list of useful options, and the lack of type mismatch checking means finding type mismatch bugs at compile time, which seems pretty silly.
I'm also baffled as to why there's both a datetime type and a struct_time type. You'd think that something as basic as date/time representation would be baked in...
