Yes, for better performance, hyperscan will ignore the from attribute by default, you need use the SOM_LEFTMOST flag when compile the pattern.

@flier thanks for this

I tried with "iuml" flag and gives me a weird result, it repeats the BtcAddressPattern multiple time as there is only one occurence.

Yes, hyperscan will reports all the matching, you need merge the matches base on from..to like this.

I'll port those syntax sugars later, but you can implement them if you need something similar.
