To me the sane thing is to have print() deliver a value that, when assigned back to a scalar, will result in the same value.

I think the following is rather pathetic: 

C:\>perl -le "print sqrt(3);"
1.73205080756888

C:\>perl -le "print 'WTF' if 1.73205080756888 != sqrt(3);"
WTF

That should be expected for integer values, but for literal floating point values you would in general have to write them in a number base of a power of two if you want to express (and match) them exactly. In that sense print() cannot be of use to do the sane thing because information is already lost due to conversion to base ten (see commensurability).
