Comment (by simonpj):
All the existing machinery for literals is oriented for relatively short,
human-readable literal strings. It's unsurprising that it chokes on
100Mb.
But it seems like an absolutely legitimate request to me. Happy needs
this too, in the form of its parsing tables; albeit they aren't so big.
There's even a wiki page about it: [wiki:StaticData] spun out of #5218.
This must be do-able, but it would need someone to lead on it.
