Towards a better BBCode

Hello {spoiler /prog/}.

What do you think of my {sup new} syntax for {i {sup B}{sub B}code} based on S-expressions? It supports {b.i.u function composition} and {sup*2 iteration {sub*3 (and nesting, obviously)}}. It uses curly braces {m \{\}} rather than the traditional {b (}parentheses{b )} because that will require less escaping.

{aa No more unmatched or misnested tags!}

I've written a {spoiler.i terrible} FIOC {i.m SexpCode-to-BBCode} translator, which you can find here: http://sprunge.us/KPWB?py

Hello /prog/.

What do you think of my ^new syntax for ^B_Bcode based on S-expressions? It supports function composition and ^{iteration _{(and nesting, obviously)}}. It uses curly braces {} rather than the traditional (parentheses) because that will require less escaping.

No more unmatched or misnested tags!

Replacement ideas for BBCODE are terrible. They are even more confusing. BBCODE isn't better if you optimize it for less characters. BBCODE is better if it's less confusing.
