print 0+sqrt!~/\./for 1..2e4

As a slight drift, how did I manage to get away without a space before the 'for'?
Because you only need spaces if the concatenation of the two tokens creates a longer leading token. But in Perl, no token starts with '0f', hence perl knows '0' is a token, and 'for' another.
