BTW, CLHS contains exactly this example of modifying the readtable with EVAL-WHEN. Their example has all three of :load- :compile- :evaluate -- I'm unsure why, because in today's implementations, it seems like less situations should be required [*]. Maybe they wanted to play safe?

[*] Seemingly, it's only during READ-time for either loading (interpreted?) or compiling that one needs to set the read-table.  There should be no need to generate code for this in the binary fasl: it's all gone then, one would think.
