I'm guessing you are not correctly interpreting the python domain usage..

comment Is there a IsDefinedQ function?
isDefinedQ[f_, args_] := MemberQ[(First@Cases[#[[1]], f[x__] :> {x}]) & /@ DownValues[f] , args] (Obviously you would not use this for the present problem)

comment Is there a IsDefinedQ function?
Note the literal question is not a duplicate. ValueQ does not work because its argument is first evaluated. ( I suspect you need to parse the results of DownValues )

comment 1/x integration giving 0 instead of infinity
Reviewing the docs for GenerateConditions I don't see the part about turning off safety checks, or how only experts should use it and should be prepared to be happy with patently wrong results.

slick. This could probably use a little more explanation.

comment NonlinearModelFit::nrnum error
The error indicates your data probably contains some non-numeric junk. Try this: ArrayQ[data[[1, 11 ;;]], 2, Element[#, Reals] &] (the second arg is 1 or 2 depending on the dimension of the data )

comment ListLogPlot error when forcing y axes start at 0
indeed, v10 works better in the sense that it ignores the zero and respects your upper limit. use Quiet@ListPlot to suppress the message.

comment ListLogPlot error when forcing y axes start at 0
I would not say it works in 9. It generates a plot but the illegal range seems to be ignored ( both the zero and the upper limit are ignored ). @mondo if you really want a zero on your log scale you will have to work with the Ticks option.

comment Change Property without re-evaluating
for that specific example you can just do x /. Orange-> Red. I'm sure you want something more general though.
