true.! expression fails to compile with following error:

expecting any of these tokens: IDENT, CONST, +, -, *, /, //, %, |, &, ^, ~, **, <<, <, <=, ==, !=, =~, !~, >>, >, >=, <=>, ===, [], []=, []?, [, &+, &-, &*, &** (not '!')

ICR embeds Crystal::Parser as part of the binary. You need to re-compile the binary to let it work:

$ icr
icr(0.32.0) > false.!
expecting any of these tokens: IDENT, CONST, +, -, *, /, //, %, |, &, ^, ~, **, <<, <, <=, ==, !=, =~, !~, >>, >, >=, <=>, ===, [], []=, []?, [, &+, &-, &*, &** (not '!')

$ make clean && make && make install
$ icr
