Way back in the dawn of Expression 2.0 - we messed around with the
concept of providing a bit more information as part of the context.
ie Integer+strict vs Integer+lax
At the time we did not figure we knew enough about what went into
context to strictly define what is needed; and rather than going ad-hoc
and making stuff up we went directly with a Class.
Now if you guys want to fake it ...
Integer.class - is lax
Integer.Type.getClass() - is strict

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
