• a symbol atom, returns x with items sanitized to valid q names

  
  q).Q.id each `$("ab";"a/b";"two words";"2drifters";"2+2")
  `ab`ab`twowords`a2drifters`a22
  

• a table, returns x with column names sanitized by removing characters that interfere with select/exec/update and adding "1" to column names which clash with commands in the .q namespace. (Updated in V3.2 to include .Q.res for checking collisions.)
