Insanity is doing the same thing over and over again and expecting different results. — Michael Scott

Be insane if absolutely necessary.

comment Why is StringExpression faster than RegularExpression?
"The regular expression is then compiled by PCRE" — Perhaps this step doesn't happen when you manually provide a regex?

comment Underflow occurred in compilation
Well to be fair, those numbers are in underflow territory... a "straightforward" way (but terribly slow) would be to use exact arithmetic (but you can't use Compile).

comment Simple problem about shadow symbols in multi-contexts
@AlbertRetey Yes, I agree. I think this one (your question) is a better candidate. This one perhaps briefly talks about exposing only those that are necessary, but it wasn't in the context of shadowing.

comment Question regarding function definition overloading / argument passing test
@Misery You can leave out the inner () and you don't need TrueQ because < will always give True/False for real numerical values and that is guaranteed by your use of _Real. In other words, g[x_Real?(# < 1 &)] := ... is the same.
