...one of the most highly
regarded and expertly designed C++ library projects in the
world. — Herb Sutter and Andrei
Compilation times of state machines with > 80 transitions that are going to make you storm the CFO's office and make sure you get a shiny octocore with 12GB RAM by next week, unless he's interested in paying you watch the compiler agonize for hours... (Make sure you ask for dual 24" as well, it doesn't hurt).
eUML allows very long constructs but will also quickly increase your compile time on some compilers (VC9, VC10) with buggy decltype support (I suspect some at least quadratic algorithms there). Even g++ 4.4 shows some regression compared to 4.3 and will crash if the constructs become too big.
Need to overwrite the mpl::vector/list default-size-limit of 20 and fusion default vector size of 10 if more than 10 states found in a state machine
Limitation for submachines and entry actions requiring an event property.
