Typeset numeric types from output by common languages

It would be very practical if siunitx could parse, even with much intervention (i.e. without specifying options) numeric outputs for common languages. It already does this for many combinations by it doesn't work for some:

For example C++ syntax: std::complex(1.,2.) output: (1.,2.e-3) latex: 1. + 2.\times 10^{-3}\mathrm{i}

Mathematica: syntax: InputForm[1.2^6] output: 1.2^2 latex: 1.2\times 10^6

syntax: InputForm[Complex[1.,2.e6] output: 1. + 2.^6I latex: 1. + 2.\times 10^{-3}\mathrm{i}

syntax: InputForm[List[1, 2, 3]] output: InputForm[List[1, 2, 3 + 4. I]] latex: {1, 2, 3. + 4. \mathrm{i}}

FORTRAN: syntax: CMPLX(1.2, 2.1) output: (1.2,2.1) [same as C++ complex] latex: 1.2 + 2.1\mathrm{i}

Some other numerical output shared by many languages can include 'nan' (or 'NaN') or 'inf' (or 'INF'), which can be interpreted as its literal name (e.g. \mathrm{inf}) or --possibly-- more fancy \infty). Other languages to look at are Matlab and Maple.
